The 100 Words Adults Misspell Most, With a Trick for Each

Most adults who worry about their spelling do not misspell hundreds of words. They misspell the same twenty or thirty, over and over, for decades. "Definately" in an email to a client. "Seperate" in a report. "Recieve" on a form that other people will read. Each time there is a small flush of embarrassment and a quick trip to a search engine, and the next time the word comes up, the whole cycle begins again.

This page is meant to break that cycle. It collects 100 words that adults get wrong most often, grouped by the reason they go wrong, with the usual mistake and one short trick for each. The tricks are not magic. What each one does is point at the exact letter that causes the trouble, which is precisely where your attention needs to go.

Treat it as a reference: bookmark it, search it, come back to it. But read the last three sections too, because a list on its own will not change your spelling, and how you practice matters more than what you read.

Why the same words catch everyone

English spelling is far less chaotic than its reputation. In a large 1966 study of about 17,000 words, Paul Hanna and his colleagues found that roughly half could be spelled correctly from their sounds alone, and most of the rest follow patterns once you take meaning and word history into account.

The words on this page live in the difficult remainder, and they fail for a small number of reasons. A vowel you cannot hear clearly. A double letter where you hear a single one. A letter nobody pronounces. A second word that sounds identical. An ending that changes the letters before it. Knowing which reason applies to a word is half of fixing it.

There is a second reason the errors persist, and it has nothing to do with intelligence. Every time you write "seperate", you practice "seperate". After years of rehearsal, the wrong form feels right and arrives first. That is simply how memory works, and the cure is to practice the right version often enough, and at the right intervals, for it to take over.

Doubles in the middle

These words hide a double letter you cannot hear, or tempt you to double one that stays single.

Doubles where word parts meet

Here the double is no accident: it appears where two parts of a word join, or where the doubling rule applies to an ending. Once you see the parts, the spelling explains itself.

Vowels you cannot hear

In English, an unstressed vowel usually collapses into a weak "uh", which linguists call the schwa. It can be spelled with any vowel letter, so your ear offers no help at all. The schwa lies behind more adult spelling errors than any other single cause, and schwa, the lazy vowel explains it fully.

Endings you cannot hear

The same problem, at the tail of the word. The ending sounds like "unce" or "uhble", and you have to choose the letters.

Those last three show a useful tendency. When the part before the ending is a complete English word, the ending is usually -able; when it is not, it is often -ible. The pattern has exceptions, but it beats guessing by a wide margin.

Letters nobody says

Most of us pronounce these words with a letter missing, and then spell them the way we say them.

I before E, and when it is not

The old rhyme works for a fair number of words and fails for plenty of others. These are the ones adults stumble on most.

Letters that change when an ending is added

These errors come from rules for adding endings, usually applied backward. The drop-the-e rule explains the logic behind most of them.

Said one way, spelled another

Sometimes our pronunciation drifts from the spelling; sometimes the spelling preserves an older form. Either way, the spoken word leads you astray.

Words that sound like other words

These are special, because a spell checker will never flag them: both spellings are real words, and only meaning decides. There are dozens more, with examples, in affect or effect and 40 other confused pairs.

The -cede, -ceed and -sede family

This small family generates a steady supply of errors, yet it has almost no exceptions to learn.

Borrowed words that kept their spelling

English has taken these from French and elsewhere with the spelling intact, which is why sounding them out fails.

Just plain hard

A few words belong to no family. Learn them one at a time.

Do memory tricks really work?

Tricks like "a rat in separate" are mnemonics, and the honest answer is that they help less than their fans believe, and in a narrower way. In 2013 John Dunlosky and colleagues reviewed ten popular study techniques and rated the keyword mnemonic, the most studied kind, as low in overall usefulness: it helped in some situations and faded quickly in others.

For spelling, a trick earns its place as a pointer. It tells you where the trap sits in a word. It does not, on its own, write the word into long-term memory. What does that is retrieval: Henry Roediger and Jeffrey Karpicke showed in 2006 that testing yourself beats rereading by a wide margin. So let the trick show you where to look, and let self-testing make the spelling stick. There is a fuller verdict on which tricks deserve your time in mnemonics for spelling.

How to learn your words without learning all 100

Do not try to learn the whole page. You already spell most of these correctly. The aim is to find your own fifteen or twenty and fix those.

Start with a test. Have someone read each table aloud while you write the words, and mark every one you miss, even by a single letter. Those misses are your list. Then practice it for about ten minutes a day: hear the word, write it from memory, check it at once, and read the trick for any letter that failed. When you spell a word correctly on three separate days, retire it.

Spread the work across two or three weeks. A word revisited after a gap of days is remembered far longer than a word repeated ten times in one sitting, the spacing effect that Nicholas Cepeda and colleagues confirmed across hundreds of studies. Spelling.School schedules those gaps automatically, though a notebook and a calendar can do the same job.

Your next step

Pick the table that feels most like you. Test yourself on it tonight, write down what you missed, and test those words again tomorrow and again in three days.

A month from now, most people find that their worst words are no longer their worst words, and the embarrassment fades with them. Adult misspellings are nearly always a gap in teaching, not a flaw in the person, and gaps can be filled at any age. If you want another angle on the classics, commonly misspelled words and tricks to remember them covers them in a different way.

Questions people ask

What is the most misspelled word in English?

There is no single official answer, because the result depends on whose writing is studied. Lists built from large samples of real writing regularly put "separate", "definitely", "accommodate" and "occurred" at or near the top. These words share the classic traps of English spelling: a vowel you cannot hear clearly, or a double letter where you hear a single sound. Most adults misspell only a small set of words, not hundreds.

Why do adults keep misspelling the same words?

Adults keep misspelling the same words because every wrong spelling is also practice. After years of writing "seperate", the wrong form feels familiar and comes out first. The trouble usually sits in one letter, such as an unstressed vowel or a doubled consonant. Practicing the correct spelling from memory, spread over several days, gradually replaces the old habit.

Do memory tricks work for spelling?

Memory tricks help, but mainly by pointing at the tricky letter in a word. A 2013 review of study techniques by John Dunlosky and colleagues rated keyword mnemonics as low in overall usefulness, because their effect is often weak or short-lived. Tricks work best combined with self-testing, where you write the word from memory and check it. The trick shows you where to look, and the testing makes the spelling last.

How can I learn 100 spelling words fast?

You rarely need to learn all 100, because most adults already spell the majority correctly. Test yourself first and pick out the fifteen or twenty you actually miss. Practice those for about ten minutes a day by hearing each word and writing it from memory, then checking it. Spread the practice over two or three weeks, since spaced practice is remembered far longer than cramming.

Which words are misspelled most in emails?

In work emails, frequent errors include "definitely", "separate", "receive", "accommodate", "necessary" and "occurred". Words that sound alike, such as "their" and "there", "your" and "you're", and "affect" and "effect", are also common. Spell checkers catch most of the first group but miss the second, because both spellings are real words. Reading an email aloud before sending it catches many of the sound-alike errors.

Is it alot or a lot?

The correct form is "a lot", written as two words. "Alot" is one of the most common mistakes in informal writing, but it is not a standard English word. A simple check is to compare it with "a little", which nobody writes as one word. In formal writing, "many" or "much" often reads better anyway.

Fix the words you actually get wrong

A few minutes a day, spaced repetition, built only for spelling. Try five words without signing up.
