Certain words in English lend themselves to misspellings. They may cause confusion about whether to use a single letter or double letters—like “cc,” “ss,” or “pp”—or how a prefix or suffix affects a root word, or they may be words that look different from how they sound.

Even though a lot of writing today is performed digitally with built-in spellcheckers, there are instances when a spellchecker isn’t available to autocorrect poor spelling. For example, when you’re writing a message in a greeting card or writing a handwritten note to your boss.

Honing your spelling is important in all types of writing, whether professional, academic, or personal. The same survey found that 65 percent of respondents said typos were unacceptable in their professional industry, and about 77 percent said they wouldn’t be attracted to a dating prospect who didn’t know how to spell.

10 commonly misspelled words

American English can be complicated, and writers often assume that words are spelled differently than they are, which leads to common misspellings.

Although it’s not an exhaustive list, here are 10 examples of commonly misspelled words.

1 Apparent

Misspelled forms: apparant, aparent, apparrent, aparrent

There’s often confusion about whether to use one or two “p” and “r” letters, as well as whether the word ends in “-ent” or “-ant.”

2  Believe

Misspelled forms: belive, beleive

The uncertainty of using “-ie” or “-ei” in the word “believe” and other words with the same pairing (“relieve,” “deceive,” etc.) led to the creation of the following mnemonic device: “‘i’ before ‘e’ except after ‘c’ or when sounded as ‘a’ as in ‘neighbor’ and ‘weigh.’”

3 Entrepreneur

Misspelled forms: entrepenur, entrepeneur, entreperneur, entreprenur

The French origins of “entrepreneur” make this word a tricky one to spell. It has a variety of misspellings, some of which include dropping or misplacing the “r” in “-pren-”; other common misspellings have issues with the “-eu” at the end of the word.

4  License

Misspelled forms: licence, lisence, lisense

Having different letters in a word that produce the same sound can lead to incorrect spellings. In “license” the “c” and “s” are often swapped, or an extra “c” or “s” is used to form the word.

Although “licence” is not considered an incorrect spelling in the rest of the English-speaking world, when writing in American English, you should replace the second “c” with an “s.”

5  Privilege

Misspelled forms: priviledge, privelege

The last part of the word “privilege” sounds similar to how you might say “ledge,” but in the correct spelling of “privilege” there’s no “d.” The “i” before “-lege” is also tricky since some might pronounce it similarly to the short “e” sound and incorrectly spell the word as “privelege.”

6  Pronunciation

Misspelled form: pronounciation

The spelling of “pronounce” is what leads writers to spell “pronunciation” incorrectly. They use “-noun-” instead of the correct form—“-nun-”—which drops the “o.”

7  Separate

Misspelled forms: seperate, seprate

Speaking of pronunciation: How you say the word “separate” could lead you to misspell it. Depending on your pronunciation, you might exchange the first “a” for an “e” or drop the first “a” altogether.

8  Tendency

Misspelled form: tendancy

It’s common for writers to erroneously replace the second “e” with an “a.”

9  Weird

Misspelled form: wierd

The mnemonic device “i before e . . .” mentioned above makes this word particularly confusing. If you steadfastly follow this device, you’d expect to spell the word using “-ie,” as in “wierd.” But it’s, well, weird.

10  Weather

Misspelled forms: wether, waether, whether

The “-ea” in weather can cause a spelling mix-up. Since the “a” is silent, it’s sometimes dropped, or the letters are reversed as “-ae.”

Additionally, “whether” is a real word and not an incorrect spelling in itself, but when used in a climate-related context, it becomes a common misspelling of “weather.”

How to avoid common spelling mistakes

If you tend to misspell words, below are tips to improve your spelling and finally get it right:

• Remember spelling devices: Mnemonic devices, like “there’s a rat in separate,” can help you land on the right spelling of “separate” every time.
• Sound out the word: Another way to attempt the spelling of a tough word is by sounding it out. It’s effective at helping you hear distinctions in consonants and vowels.
• Check for homophones: Homophones, meaning different words that sound the same, can result in misspelled words. For example, “to,” “too,” and “two.” Pay extra attention to these words to ensure you’re using the right one.
• Break up larger words: Compartmentalizing words into smaller pieces can help you spell them correctly. For example, “independent” can be broken into “in-de-pen-dent” and “maintenance” is “main-ten-ance.”
• Consider your geography: Some words are spelled differently depending on geographic preferences. In Australia and the United Kingdom, it’s not uncommon to see the spelling “judgement,” which keeps the first “e.” The US spelling, however, drops the first “e” to form “judgment.”
• Refer to a reliable dictionary: Ultimately, turning to a trusted dictionary can help you improve your spelling. It also gives you an opportunity to check that you’ve chosen the best word for the message you want to convey.
