A wide assortment of words are frequently misspelled in English, including the word “misspelled” itself. Both native English speakers and English learners have trouble spelling many words since they do not follow common laws of spelling and they cannot be spelled phonetically, as challenging words in other languages often can be. The most commonly misspelled words can plague even experienced writers. It is an excellent idea to analyze the words that you personally misspell most frequently, in the hopes of identifying weak points in your spelling so that you can improve.
Many of the most commonly misspelled words have combinations of double letters which can be confusing and disorientating. Some of these words include accommodate, a notorious misspelled word, along with embarrassment, unnecessary, guerrilla, occasion, and commitment. The most commonly misspelled words often include a double C, which can look strange on the page since it may not be obvious when the word is spoken aloud. If a word has a hard C sound followed by a soft C as in access, accident, or accessory, it probably has a double C.
Others among the most commonly misspelled words have letter combinations which may seem unfamiliar or strange, sometimes because they are borrowed from other languages. Twelfth, acquaintance, fiery, medieval, acknowledgment, and fluorescent are some common examples of these words. The spelling patterns in these words must be individually learned; twelfth, for example, contains an awkward letter combination which you are unlikely to encounter in other English words.
Some spellers are also struggle with E's. There are words like weird which violate the “I before E” rule, and there are also words like cemetery, precedence, independent, existence, and perseverance which seem to have too many E's when spellers look at them on the page. Many spellers add A's to these words, not realizing that an E can make a sound like an A in some cases.
Other words like maintenance, conscientious, judgment, sacrilegious, privilege, and definitely are just hard to spell, and they often pop up on lists of most commonly misspelled words. Many spellers add extra letters to them, or confuse letters when they try to write these words out on the page. Another common problem is spelling a word correctly, but not realizing that the word has a homonym; principals may have principles that help them know how to run a school, for example. People also routinely mix up their/there/they're, and its/it's in writing. While not strictly misspellings, these errors can be glaring, and it is an excellent idea to review your work with an eye for these common mistakes.
