Also asked, which is correct mother's or mothers?
If you're referring to one Mother, it is Mother's. If you're referring to many Mothers, it is Mothers'.
Also, does needs have an apostrophe? Remember, a possessive noun needs an apostrophe and an "s" at the end. If there's already an "s" there, you can just add the apostrophe. If there's no "s," you have to add both - first the apostrophe, and then the "s."
In this manner, is there an apostrophe in mothers?
Mother's Day (apostrophe before the s) Father's Day (apostrophe before the s) Veterans Day (no apostrophe)
What is the possessive form of mother?
To get the plural possessive, do both those things: put the plural S on mother and the possessive S and apostrophe on law: “It was their mothers-in-law's idea.”
