Truly vs Truely: Which Spelling Is Correct?

Truly is the correct spelling, while truely is a common misspelling.

Both forms may look logical because the word comes from true, and many English words keep the final e when adding a suffix.

However, truly follows a special spelling rule: when true becomes an adverb with -ly, the final e is removed.

This creates the correct form truly, not truely. The mistake exists because English spelling rules are not always consistent, and writers may apply the usual “add -ly” pattern.

This guide explains the history, spelling rules, common mistakes, examples, and best usage of truly vs truely.

Truely is incorrect in standard English.

The word truly means genuinely, really, or sincerely.

Examples

She is truly happy with the result.
He truly believes in his work.
We are truly sorry for the mistake.

The Origin of Truly vs Truely

Truly comes from the adjective true, which has a long history in the English language.

The word true can be traced back to Old English trēowe, meaning faithful, trustworthy, or genuine. Over time, English developed truly as the adverbial form of true.

The spelling truly developed because English removes the final e from true before adding -ly.

This can seem confusing because many English words keep their final e when -ly is added.

For example:

brave → bravely
complete → completely
polite → politely
sincere → sincerely

But true is different:

true → truly
not true → truely

The form truely looks reasonable at first glance, but it does not follow the standard spelling of the word.

British English vs American English Spelling

There is no British-American spelling difference for truly.

Both British English and American English use:

truly ✅

Neither standard variety uses truely as the correct spelling.

English Variety	Correct Spelling	Example
American English	truly	I truly understand.
British English	truly	I truly understand.
Canadian English	truly	She is truly talented.
Australian English	truly	We truly appreciate it.
International English	truly	He truly cares.

Why Is “Truely” Wrong in Both?

The spelling rule does not change based on the variety of English.

The correct formation is:

true + ly → truly

The final e is removed before -ly.

So whether you are writing for readers in the United States, the United Kingdom, Canada, Australia, or elsewhere, truly is the correct choice.
