1.1Who has: who’s done the reading?...
- I join the end of the queue, nodding at a former stranger who's almost become a friend over recent months.

Usage
A common written mistake is to confuse who’s with whose. The form who’s represents a contraction of ‘who is’ or ‘who has’, while whose is a possessive pronoun or determiner used in questions, as in whose is this? or whose turn is it?.
