whose and who is

Which is correct? Whose in charge or who is in charge? I’m having a confusion with these two. Can someone please explain/tell to me when to use whose and who is?
Your help will be very much appreciated.

Can you please elaborate this one for me? When to use whose and who is?

whose is the wrong word for your sentence.
who’s is a contracted/short form of who is.

IMHO:

(1) Who’s the president of your country? = Who is the president of your country? (Who + is = Who’s)

(2) Whose book is this? = To whom does this book belong? It’s my/your/his/her/our/their book. Just as my/your/his/her/our/ their are the possessive forms of I/ you/he/she/we/they, so is “whose” the possessive of “who.” (a) When you SPEAK, of course spelling is not important. But when you write, be sure to spell “Who is” as “Who’s” and the possessive of “who” as “Whose.” That’s what native speakers have decided over the many years. (i) Who’s in charge here? = Who is in charge here? Answer: Mr. Smith is (in charge here)./ Whose job is it to make the decisions here? (It is the job of whom to make the decisions here?) Answer: It’s Mr. Smith’s job (to make the decisions here).

yes James is right. Whose is actually the possessive form of who, whose is related to possession but who is related to person.

I suggest you read this thread: Whose vs. who’s[YSaerTTEW443543]
