How to spell certain
Certain is spelled C-E-R-T-A-I-N. An E after the C, and the same -TAIN ending as curtain and captain.
What it means: Having no doubt; confident and assured.
In a sentence: She is certain that her cat loves to play with strings.
The part people get wrong
Watch for an unstressed vowel that is hard to hear.
Same family: certainty, certainly, uncertain, uncertainty, certify. If you can spell one, the shared part carries to the others.
Where it comes from: Certain comes from the Latin word 'certus,' meaning 'sure' or 'fixed.' It entered English through Old French, which is why its spelling looks less phonetic than it sounds.
