Not a question, but a correction


This is a great site, which I recommend to my students. 


However, on the apostrophe for possessives with nouns, you omitted one rule:


When you have a compound subject, you add 's to only the last subject if the object belongs to all subjects.

Ex.: Mary and Paul's mother. = Mary and Paul have the same mother.


When you have a compound subject with multiple objects that belong to each subject, you must add 's to each subject.

Ex.: Mary's and Paul's mothers. = Mary's mother is not Paul's mother.


That is all. Thank you.
