How should I use possessive case with a compound subject?

1 Answer

Answer:

There are two rules.

Explanation:

First Rule: When a compound noun both own the thing possessed, only the second element takes the possessive form.

Example:

Eliza and Maribel's house was constructed two years ago.

(They both own the house.)

Second Rule: When the things possessed are owned individually, both nouns take the possessive form.

Example:

Eliza's and Maribel's suggestions are considered during the meeting.

(They each possessed separate suggestions.)
