Grammar post #5

So this week's grammar post will be on the same grammar issue that I will be giving my presentation on next week: Subject, Verb agreement.

How do you determine the proper verb form to use with singular or plural nouns?
Obviously the most basic rule is that singular verbs go with singular nouns and plural verbs go with plural nouns. The thing that is a little odd is that singular verbs tend to end in s and plural verbs do not. This is the opposite of singular and plural nouns.
The girls talk. The boy talks.
There are many variations of this rule that can be found here but this is the first and most important rule.
