Is it wifes or wife's

Answer 1

It depends on what you are trying to say:

• Some kings had many wives (in this case, "wives" is used because the sentence is about more than one wife)
• The wife's ring is beautiful (in this case, "wife's" is used because the sentence indicates possession. The ring belongs to the wife, so it is the ring of the wife, or "the wife's ring"
• The wives' plan to surprise their husbands was a huge success (in this case, "wives'" is used because it is talking about more than one wife, so "wives" is used, and the apostrophe is needed because the sentences against indicates possession. Because "wives" ends in an s, "wives's" would be grammatically incorrect, so the s after the apostrophe is dropped, resulting in just "wives'."

Note: The last bullet also applies to all words that end in s

Hope this helps!

Answer 2

The correct form is "wife's" when indicating possession by a singular wife. For example, "My wife's car."
