The Most Commonly Misspelled Words in the English Language

Its common knowledge that English is a strange language. It has a lot of rules that contradict themselves that also have a lot of exceptions. Grammar is all over the place and proper pronunciation often doesn’t make sense. If you are not a native English speaker it can be a difficult language to learn.

With all the rules and nuances, there are a lot of words that can be tricky to spell. Here are some of the most commonly misspelled words in the English language – and some tips to remember how to spell them!

This word is not pronounced exactly how it looks so spelling can be tricky. Just remember that it makes “sence” to spell it with an E!

The ending of words like “acceptable” are often confused with “ible” as it sounds similar when reading out loud. Just remember to “accept” the “table” that you are being offered.

Double consonants can be hard enough to remember, forget two in the same word! Just remember that this word is large enough to accommodate two C’s and two M’s.

Remember that both Ds are being delivered to the same address.

Having your own “ally” is a “basic” part of life.

Many learn from a young age to remember that I comes before E except after C. Believe is a word where this rule applies.

The confusion here often comes from the E. Remember that “change” keeps its E and thus makes the G soft rather than hard.

Column is not the only word of its kind in the English language, just remember that although it may not have an obvious purpose… a silent N after an M is common.

This one is simple – don’t let yourself be conned by a “science” nerd!

Often confused with defiantly. Remember that Definitely carries its silent E with it wherever it goes.

This is another long word – long enough to fit two Rs and two Ss without getting squished.

When adapting to a new environment, you may have to “iron” out some kinks.

Putting two A’s in the same word can be an exhilarating experience!

This word breaks the I before E except after C rule – what a foreign concept!

Take pity on the poor R in this word… it is so weak that it needs an O on either side of it in order to stay standing.

Don’t spell this word with an “ence,” that would be downright ignorant!

Remembering the two L’s and the “ence” ending are signs of great intelligence.

The confusion with this word often comes in the beginning, where the E and I are mixed up. Just remember that you do not have to tell a lie to experience some leisure.

Often confused with “loose.” Lose the extra O and spell this word right every time.

“Main” and “tenance” are the primary tenants of this word.

You will hear lots of neighing from next door if your neighbor has a horse farm.

The Es in this word are only able to persevere until the last syllable, where the A takes over.

Don’t take it personally that this word needs two Ns!

This word is in possession of more S’s than most hissing snakes!

When something rhymes, it has a nice rhythm – these words go well together at times.

Remember that a secretary will always keep your secret!

You must write this word with an A after the E whether you like it or not.

This is one of the weirdest exceptions to the I before E except after C rule.

How to Make a Great Crossword Puzzle

If you’re a logophile, or word-lover, then you know that there are few greater joys than completing a crossword puzzle. The clever mix of clues and cunning use of simple and play-on-words answers mean you can spend hours lost in thought and word definitions. If you’re one of the millions of people who love spending Sundays with the New York Times’ Crossword Puzzle, the next time you want to flex that puzzle-solving muscle, consider making your own. Here are six steps to creating a great crossword puzzle.

Narrow Down Your Audience

The first step in making a crossword puzzle is choosing an audience. You’ll make a very different kind of puzzle if your audience is kids, college students, adults or industry-specific employees. The audience will influence the level of difficulty, theme, answers and clues. If you want to try and sell your puzzle to a specific publication, make sure you are familiar with the types of puzzles that publication usually includes.

Choose a Theme

With your audience in mind, choose a theme that will link the answers in the puzzle. It can be something as simple as “house.” This theme would then guide the creation of the puzzle, meaning the long answers in the puzzle would have to do with parts of a house. You can be more creative than this too, but when first starting out it’s easier to keep your theme simple. The best themes are narrow and consistently applied throughout the puzzle.

Another common way to choose a theme is to pose a question. The answer to the question would be made up of the longer answers in the puzzle. With this kind of theme, sometimes people are able to answer the thematic question before they can solve the individual clues.

You can draw inspiration for the theme from your favorite puzzle makers, everyday objects around you, subjects you’re passionate about or even your kids. As you brainstorm about your theme, list all related words that come to mind and their letter count. This will help later on with answers.

One caveat to this step is that not all crossword puzzles have a theme. However, picking a theme will make the other steps easier. Themes also make the puzzles easier and more enjoyable for your audience.

Design the Grid Layout

Once you select a theme, the next step is setting up the grid. The grid is the mix of black space and white boxes where your audience will fill out answers across and down. It’s best to start small and then work your way up to more complex grids. In general, grids are symmetrical, but some puzzle makers get creative and use grids that look like animals or other shapes.

To this day, the New York Times follows the same rules established by the paper’s first crossword editor, Margaret Farrar:

  • Use an odd number of squares on a side
  • The grid should have 180-degree symmetry
  • Black squares should make up no more than 1/6th of the grid
  • Word count should be between 72 (if no theme) and 78 (for a grid with 15 squares across)
  • The theme-based answers should be in symmetrical positions in the grid

Of course, you don’t have to follow the New York Times’ example. As you work on crosswords yourself, take note of the layouts of those puzzles. Try out different layouts and see which one you like working with or is most appropriate for your desired audience.

Fill in the Grid with Answers

The next step is creating the answers. Yes, you decide on the answers before you come up with the clues. This may seem counterintuitive, but it is how you ensure that all of the words will fit into the grid.

Here are some general rules of thumb for coming up with answers:

  • Start with the longest answers first
  • Then work across and down until you hit a corner
  • Do not repeat answers
  • When choosing answers for the words that go across, follow a pattern of “vowel, consonant, vowel, consonant” or vowel-heavy words since they will give you more flexibility for words that go down
  • If a word going across requires specialized or advanced knowledge, keep the words going down a little easier
  • Consonant-heavy works are more difficult to work into a puzzle
  • Theme-based answers should have the same letter count (contributes to the symmetry of the puzzle)

It can also be fun to try and work in a “marquee answer” or an answer that is a new phrase, something relevant to the news or pop culture, etc. You can also try to work in secret messages in your puzzles too for additional fun.

There are autofill programs that can fill in the grid for you, but it’s more fun to come up with the answers yourself.

Create Clues that Tie to the Answers

Writing clues is probably the hardest part of the puzzle. While you can put straightforward clues such as “equipment used in baseball” for a three letter answer of “bat”, the real fun of crosswords comes from making the person solving the puzzle really think. You want the person working on the puzzle to spend enough time solving the clues so that they feel clever and smart when they figure out the answer, but not so long that they get frustrated and abandon it.

Clues should be entertaining and witty and make liberal use of gimmicks and wordplay. If you are trying to come up with a new word or definition, check out WordsAPI. Our tool can help you find related words, definitions and more with our easy to use API for the English language. It’s a fun way to play with the English language – something that every great crossword puzzle maker does.

After you’ve developed a knack for writing clues, you can then advance to the New York Times’ standard of never repeating a word in the answers or the clues.

Review the Puzzle to See if You can Make it Better

With a draft of your theme, grid, answers and clues complete, take time to review your puzzle to see if anything can be tightened up or made more relevant to the theme. Let a friend test it out and ask for feedback.

Also, be sure to fact check your clues. Even if a clue and answer come from your area of expertise, it’s always good to double-check.

Get Started on Your First Crossword Puzzle Today

No matter your motivation – for fun or for publication – you can start working on designing a great crossword puzzle today. If you love the English language and playing with words, making puzzles is a fun and easy way to indulge in this passion. Making puzzles can also help you build skills to complete puzzles more quickly and easily. With a better understanding of how puzzle makers think, you’ll be better able to intuit answers and solve clues.

How to Build a Word Definition Widget with WordsAPI

One of the most common uses of WordsAPI is to let users look up definitions for words.  It's incredibly easy to accomplish - we'll do it in less than 100 lines of javascript.  If you want to see it in action, here it is.

We'll start by creating a simple form that will auto-suggest words as the user types. We'll add some simple styling using the Yahoo Pure css library.  We'll also add in an unordered list where the results will be displayed.

<form onsubmit="return false;" class="pure-form" style="border-top: 1px solid #eee;border-bottom:1px solid #eee;background:#fafafa;margin:30px 0;padding:20px 10px;text-align:center">
  <input id="user-input" autofocus type="text" placeholder="Type a word ..." style="width:100%;max-width:600px;outline:0" />
<ul id="definitions"></ul>

For the auto-complete functionality, we'll be including a small library from Pixabay. This library will handle populating the suggestion list that we get.  The library needs a function to call when the users types. We'll configure the library using the code below. The source attribute is a function that gets called when the user types. It sends in a term, and waits until a list of suggestions are provided.

new autoComplete({
  selector: "#user-input",
  minChars: 1,
  source: function(term, suggest) {
    getSuggestions(term).then(response => {
  onSelect: function(e, term, item) {


The getSuggestions function is where we'll link into WordsAPI. You'll need your own API key, which you can get from here. The function makes use of the WordsAPI search capabilities by providing a letterPattern that will match any words that start with the letters the user has provided, as well as restricting the results to only words that have definitions.

function getSuggestions(input) {
  const url = `https://wordsapiv1.p.mashape.com/words/?letterPattern=^${input}.*&hasDetails=definitions`;
  return fetch(url, {
    method: "GET",
    headers: {
      "Content-Type": "application/json",
      "X-RapidAPI-Key": apiKey
  }).then(resp => resp.json());

When the users selects a word from the suggestions list, the onSelect attribute of the autoComplete library will get called.  This will pass the results to the getDefinitions function, defined below.  This function again calls out to WordsAPI, this time to get the definitions of the selected word.

function getDefinitions(term) {
  const url = `https://wordsapiv1.p.mashape.com/words/${term}`;
  return fetch(url, {
    method: "GET",
    headers: {
      "Content-Type": "application/json",
      "X-RapidAPI-Key": apiKey
    .then(resp => resp.json())
    .then(resp => {
      return resp.results;

Finally, we'll show the results in a list below the input field in our showDefinitions function.

function showDefinitions(definitions) {
  definitionList.innerHTML = "";
  definitions.forEach(definition => {
    const li = document.createElement("li");
    li.textContent = `${definition.partOfSpeech} - ${definition.definition}`;

And that's it! You can see a fully working version at this CodePen.

Why English is Weird

Approximately 1.5 billion people, roughly 20% of the world’s population, speak English. Only 350 million or so are native speakers, meaning the remaining 1.15 billion learned it as a foreign language. It’s the most widely studied second language and the default common language for many international businesses and travelers.

While these figures make it seem like it’s easy to pick up the language, many learners will probably beg to differ. English has many oddities that make it one of the harder languages to learn, despite how widely it is spoken.

Effective Ways to Learn English

There are many methods for learning languages. Classroom instruction tends to focus on learning grammar, spelling and pronunciation rules. As students learn one word, it’s only natural that they would apply the same rules to a similar looking word or similarly-structured sentence. This might work in some languages; English is not one of them.

This is often why many language learners report having better success picking up English from movies or TV. They get to hear how it is actually spoken and start to develop that native sense of when something “sounds right.”

No matter which method learners choose, they could benefit from keeping these quirks in mind.

Word Meanings

Consider these examples:

  • Pineapples do not contain any pine or any apples
  • Hamburgers are not made of ham
  • A pocketbook is not a book and it doesn’t fit into your pocket
  • Eggplants don’t have egg in them

These inconsistencies can make it harder to deduce the meaning of a word. While a new English speaker may understand part of the word, this does not necessarily mean that the speaker will grasp the meaning of the full word.

English also has a long list of homophones, homographs, homonyms, heterographs and multinyms. Most native English probably don’t know these terms, but they are familiar with the words.

  • Homophones: same sound, different meaning, ex: to, two, too
  • Homographs: same sound and spelling, different meaning, ex: bow (front of boat and to bend at waist)
  • Homonyms: same spelling, different meaning, ex: live, wound, wind
  • Heterographs: same sound, different spelling and meaning, ex: know, no
  • Multinyms: same sound, two or more different spellings and meanings, ex: raise, rays, raze, etc. 

How do you explain these differences, and so many more, to students? ESL students probably hear the phrase, “that’s just how it is” more times than they care to.

Spelling and Pronunciation

While English has some spelling rules such as “I before E except after C”, these are quickly violated as soon as a student learns the words science and weird. One grammarian says that only 44 words actually follow that rule while 923 don’t.

Another rule is that plurals are created by adding an s or es to the end of a word. But alas, mouths contain teeth not tooths, more than one mouse becomes mice and more than one moose becomes…moose.

In theory, spelling also affects pronunciation. However, English also has a lot of silent letters. In knife and gnome, for example, the first and the last letters are silent. There are also letter combinations that can lead to wildly different sounds. Take trough, rough, bough and through for example. In many situations, English is just not phonetically consistent.

Again, with these exceptions, learners are often told that they just need to memorize the different spellings and pronunciations.

Verb Tenses

Sometimes English verb conjugation is considered easy to learn because there generally aren’t different spellings depending on the subject. For example, I go, you go, he goes, we go, they go, and for past tense I/you/he/we/they went whereas the equivalent in French would have multiple spellings. In general, the past participle will be formed by adding -ed or -d to the end of the word. For example, to face becomes faced and to live becomes lived. But of course, there are irregular verbs and exceptions.

  • The past tense of fight is fought
  • The past tense of light is lit
  • The past tense of read is read
  • The past tense of feel is felt
  • The past tense of drive is drove
  • The past tense of wake is woke
  • The past tense of have is had

English also gets complicated when it comes to the future. There are many ways to talk about the future, each with their own subtleties. For example, here a few ways someone can say they are going to consume dinner at a later time:

  • I’ll get dinner
  • I’m going to have dinner
  • I was going to have dinner
  • I’m getting dinner

There may be general rules that learners can follow, but there are likely just as many, if not more, exceptions that they will have to remember as well.

Order of Words

English can also be a little peculiar when it comes to word order. In general, most sentences will follow a subject – verb – object order. However, depending on the word, adjectives and adverbials can fall in multiple locations in a sentence. For example, one can say I ate quickly or I quickly ate, but one can only say I stayed long not I long stayed.


A common grammar mistake even among native speakers is the use of apostrophes. They can be used as a contraction where he is going becomes he’s going. However, they can also be used to denote possession. Instead of saying the toys belonging to Sarah, speakers simply say Sarah’s toys. The exception to using an apostrophe to denote possession occurs with the word it.
It is warm becomes it’s warm
To describe the leaves of a tree falling off, one would say the tree lost its leaves

Native speakers will likely be forgiving of this error as non-grammar-lovers make this mistake frequently themselves.

Don’t Get Discouraged

English can be hard to learn. The rules all seem to have exceptions and there’s a lot about the language, its spelling, pronunciation, grammar and more that doesn’t quite make sense. But people who want to become fluent in this global language shouldn’t get discouraged. Its popularity also means that there are ample resources for helping students learn. WordsAPI, for example, is an online source to find definitions, synonyms, antonyms, word hierarchies and much, much more.

Searching for Words by Detail Type

We've expanded the Words API search functionality so that you can now search for words that have one or more detail types.  For instance, if you wanted to find words that have both "hasUsages" and "hasCategories" relationships, you would call the API like this:


  "query": {
    "hasDetails": "hasUsages,hasCategories",
    "limit": 100,
    "page": 1
  "results": {
    "total": 7,
    "data": [

You can also use this to search for random words, like so:


  "word": "gloaming",
  "results": [
      "definition": "the time of day immediately following sunset",
      "partOfSpeech": "noun",
      "synonyms": [
      "typeOf": [
        "time of day"
      "hasTypes": [
      "partOf": [
  "syllables": {
    "count": 2,
    "list": [
  "pronunciation": {
    "all": "'gloʊmɪŋ"
  "frequency": 1.73

The Long Tail of the English Language

In the English language, the most common words are incredibly common.  Though there are at least 1 million words in the English language, "you", "I", and "the" account for 10% of the words we actually use. By the time you reach "is", at number 10, you've covered 20%.

The top 100 most common English words account for over 50% of the words we use, which is about how many words a 2-year old know. A 3-year old would probably know most of the top 1,000 words, which covers 75%.  And by the 10,000th most common word, "remorse", you've covered over 88% of the words we commonly use. That leaves a lot of words you don't hear very much.

If you put word frequency on a graph, like the one below, you quickly see an interesting distribution called the Long Tail.  It happens when a small number of items account for a disproportionate number of occurrences, such as the books that Amazon sells.

You can search for words to see where they fall on the graph by typing the word into the Search box.

It's somewhat heartening to see that "good" is more common than "evil" (58th vs 978th), "love" more common than "hate" (110th vs 527th), and "happy" more common than "sad" (272nd vs 844th). But "war" is still more common than "peace" ( 492nd vs 797th).

Many words occur just once every million words, like "icing", or even less.  Tremulous, meaning "quivering as from weakness or fear", occurs 0.04 times per million words - meaning you'd hear it about once ever 25 million words. Some word occur so infrequently we didn't even find samples of them, even though we counted almost 70 million of them.

If you're interested in using Words API to find word frequency information, be sure to check out the documentation.  If you're interested in seeing how we got this data, be sure to read this earlier post about our open source tools.
