Verbs
You mean 'adjectives', which are describing words. Verbs are doing words.
Verbs are the words that say what a subject is (being verbs) or does (action verbs). Nouns are words for persons, places, things, or ideas. Pronouns are words that take the place of (stand in for) a noun. Adjectives are words that describe nouns.
If you mean what are the root words, there are none because only verbs have root words and those are not verbs.
Because verbs show actions or states. Other words, adverbs, are used with verbs to form negatives.For example not is used to form the negative of the verbs be, do and have and modal verbs like can or must and often shortened to n't.
Verbs are not describing words, adjectives describe nouns. Verbs are action or being words. Some examples of verbs for snowmobiling:godon't gowentlovehatewaswill bewon't be
Verbs do not describe things- those are adjectives. Verbs are action words.
Some example of verbs for an act (action verbs):actbringchewdrilleducatefindgohireirkjumpkneellaughmissSome examples of verbs to be (being verbs):amarebebeenbeingiswaswere
"Adverbs" are the words that modify verbs, adjectives and other adverbs.
Words like action, occurrence, event, or activity can be used to describe verbs. Verbs convey an action or state of being in a sentence.
The words highly and hastily are neither verbs nor adjectives. Both words are adverbs.
