English is famous for its challenging spellings and pronunciations. To use a popular example, we have “tough,” “through,” “though” and “trough,” each ending in “ough” and each pronounced wildly differently. This is likely why English is one of the only languages with spelling bees: other languages have spelling that is so predictable, there’s not much guesswork involved in spelling.

We took on the task, then, of looking at some of the hardest words to spell. None of them are rare — yes, there are chemistry terms that are very difficult, but those aren’t very interesting — but each of them has gotten us a squiggly red line when we’ve written them before. After that, we tackle the hardest words to pronounce, which have their own quirks to uncover.

The Hardest Words To Spell In English

In English, there are two main reasons for why a word might be hard to spell. One is that it comes from another language, which means that the spellings reflect that language and not English. Of the 10 words we list below, all 10 trace their roots back to a different language. Another is that English pronunciation has changed but the spelling of a word has not. The word “Wednesday” for example used to be pronounced similar to how it’s spelled, but over time has been shortened to “WENNS-day.”

Top 10 Hardest Words To Spell

1. Accommodate: Originating from Latin, this word is often misspelled as “accomodate” or “acommodate.” Remember, it has two c’s and two m’s.
2. Conscientious: This word, derived from Latin, is frequently misspelled as “consciencious.”
3. Rhythm: Borrowed from Greek, this word often appears as “rythm” or “rythym.” It has no vowels except y, which is rare in English.
4. Supersede: Often misspelled as “supercede,” this word comes from Latin.
5. Indict: This word, borrowed from Latin, is often misspelled as “indite.” Remember, the c is silent.
6. Pharaoh: Originating from Egyptian, this word is frequently misspelled as “pharoah.” The a comes before the o, which isn’t very common in English..
7. Pronunciation: Often misspelled as “pronounciation,” this word comes from Latin. One tip is to think of how it’s pronounced “pro-nun-ci-a-tion,” not “pro-noun-ci-a-tion.”
8. Bureaucracy: Borrowed from French, this word is often misspelled as “bureacracy.” It may be easier to spell if you pay attention the fact it has “bureau” in it.
9. Quarantine: This word, derived from Italian, is frequently misspelled as “quarentine.”
10. Fuchsia: Often misspelled as “fuschia,” this word comes from German. It can be helpful to know it’s named after the botanist Leonhart Fuchs.

The Hardest Words to Pronounce in English

What makes a word hard to pronounce is a bit different from what makes it hard to spell. You might have no trouble spelling “sixth,” but that cluster of consonants at the end can trip up any tongue. Phonetic complexity, unfamiliar sounds and tongue-twisters will have even the most skilled speakers stumbling for words.
