The Origin of Whose or Who’s

Understanding the origin of these words helps explain why confusion exists.

Origin of “Whose”

The word whose comes from Old English hwæs, which was used to ask about ownership. Over time, it became the possessive form of who. Unlike most possessive forms in English, whose does not use an apostrophe. This exception often confuses learners, but it follows historical grammar patterns.

Origin of “Who’s”

Who’s is a shortened form created by contraction. English commonly combines words to make speech faster and more natural. Who’s combines:

• who + is
• who + has

The apostrophe replaces the missing letter. This is why who’s never shows possession.

The spelling difference exists because one word shows ownership (whose) while the other simply shortens two words (who’s).
