her family's or families van was confortable. which is the correct possessive form of the noun?
Since the van belongs to the family, family must be possessive -- family's.
The correct possessive form of the noun "family" in this sentence would be "family's."
To determine the correct possessive form, you need to consider whether the noun is singular or plural. In this case, we are referring to a single family, so the noun is singular.
To indicate possession, we add an apostrophe (') and the letter "s" after the noun, as in "family's." This form is used to show that the van belongs to or is associated with the family.
If the sentence was referring to multiple families, the possessive form would be "families'".
