How to spell fifteenth
What it means: The day next after the fourteenth of a month.
In a sentence: The school's art show is on the fifteenth of April.
The part people get wrong
Watch for double e. Often misspelled as fifthteenth or fiveteenth.
Same family: fifth, fifteen, fiftieth, fifty, fifteenthly. If you can spell one, the shared part carries to the others.
Where it comes from: Fifteenth comes from the Old English words "fīftiēne" (fifteen) and the ending "-tha" used to form ordinal numbers. Over time, the spelling and pronunciation changed, but the -th ending still marks it as an order number, like fourth, tenth, and twentieth.
