accommodate

Study the spelling, then hide it and type it from memory.

Hard-to-spell words are rarely hard at random: almost every one hides a double letter, a silent letter, a foreign borrowing, or a suffix that breaks the usual pattern. Once you know why a word trips people up, you can attach a memory hook to that exact trap instead of rote-drilling the whole word. The groups below sort notorious misspellings by the specific difficulty they contain.

Double-letter traps

These words are missed because writers drop one of a doubled pair or double the wrong letter, as in accommodate, which needs both a double c and a double m.

Silent letters

These words contain letters you cannot hear when the word is spoken, so the ear gives the hand no help at all.

Borrowed from other languages

These words keep the spelling conventions of the language English took them from, so Greek gives ch the k sound and French leaves whole syllables unwritten.

Suffix and ending traps

These words go wrong at the ending, where -ally, -lly, and the sci letter cluster defy the way the word sounds.

Unusual letter patterns

These words combine letters in sequences that look wrong even when they are right, which makes writers second-guess a correct attempt.

Base words and their tricky forms

These base words are hard on their own, and adding an ending or a possessive raises fresh doubling and apostrophe questions.

Frequently asked questions

What are the hardest words to spell in English?

Words that combine several traps at once top most lists: accommodate stacks two double letters, conscience hides an unexpected sci, millennium doubles both the l and the n, and Wednesday buries a silent d. Borrowings like silhouette, camaraderie, and choreography are hard because they follow French or Greek spelling habits rather than English ones. If a word makes you hesitate, it almost certainly contains one of those patterns.

Why are some English words so hard to spell?

English absorbed vocabulary from Latin, French, Greek, and Germanic languages while keeping each source's spelling habits, so one sound can be written many ways. Pronunciation also drifted over the centuries while spelling froze, which is how silent letters in words like solemn and receipt survived. The result is a spelling system where the ear is an unreliable guide.

How can I get better at spelling difficult words?

Target the trap, not the whole word. For accommodate, remember it is large enough to accommodate two c's and two m's; for conscience, spot the word science hiding inside it. Writing a troublesome word out by hand a few times in a real sentence fixes it far better than staring at a list, and keeping a personal log of your own repeat offenders tells you exactly where to spend effort.

Is it misspell or mispell?

The correct form is misspell, with a double s. The prefix mis- attaches to the base word spell, and both keep their letters, so the s from mis- and the s from spell sit side by side. Misspell itself is one of the most commonly misspelled words in English, which writers tend to find either comforting or cruel.
