Point out the different forms of the verb that are used with the
different subjects:—
=Singular.= =Plural.=
First Person. I write. We write.
Second Person. Thou writest. You write.
Third Person. He writes. They write.
The different forms that a verb takes to agree with the person and
number of its subject are called =person= and =number= forms.
Observe that there is no change in the action expressed by the verb; it
has merely adapted itself to the person and number of its subject.
The third person singular has, in the present indicative, the ending _s_
or _es_, and the old form _eth_; as, He _walks_; He _goes_; He
_dreameth_.
The second person singular has the ending _est_ or _st_ in both the
present and the past tenses; as, Thou _lovest_; Thou _lovedst_.
The first person singular and the plural forms for all the persons have
no endings to mark person and number, with but one exception, the verb
_to be_; as, I _am_; We _are_; I _was_; We _were_.
