The simple present is the form of the word used with a subject like people, Mr. Jones, I, dog, etc. It makes a statement about something that is true in the present time.
I live in Kentucky.
Mr. Jones lives in Idaho.
People live all over the place.
I wag my finger.
The dog wags its tail.
One of the beauties of English grammar is that our verbs don’t have numerous endings. The simple present has only two forms. Ex. wag/wags.
Error prevention: The most common error relating to the use of the present form of the verb is leaving off the s when it’s called for, or tacking it on when it isn’t needed.
Who knows? In another hundred years or so, that s may disappear as all the other endings have.
