For example:

She loves you
They are running
Go there on Monday
He said, "hello!“
Can you play the piano?

Derived verbs
Derived verbs are formed through affixes.
An affix is a meaningful element added to another meaningful from resulting in a free form or a word.
Derivation is the process whereby the addition of affixes, chiefly prefixes and suffixes in English, to base forms results in the creation of new words.
Suffixes: -en, -ate, -ize, -ify
Prefixes: be-, en-
For example: material-ize=materialize
deep+en=deepen
pure+ify=purify
active+ate=activate

Compound Verbs
If a subject of a sentence has a verb that is made up of more than one word, that verb is called a compound verb.
