Verb Spelling: 3rd Singular Persons

PRESENT SIMPLE
VERB SPELLING: 3rd Singular Persons

It's important to notice that English presents easy verb conjugation models, but even that the Present Tense affirmative sentences shows some interesting verb variation endings.

For example we can compare these sentences:

              A                                                       B                                                           C
I come from Italy.                    Karl comes from Italy.                This machine comes from Italy
We go to the movies.               Ruth goes to the movies.            Ariel goes to the movies.
You study History.                  Sheila studies the weather.        Thomas studies this case.


Obviously, there is a notorious verb ending variation between sentences in column A in relation to column B and C.
