Verbs--Action, Helping, Linking
**Helping verbs "help" out the main verb in a sentence. In order to have a helping verb, you must have a main(another) vreb in the sentence to help.
Ex. She is riding to the store. is--helping verb because it helps out "riding"---action verb/main verb
Two or more verbs working together in the sentence is called: verb phrase
Ex. She should be cleaning the room. should be cleaning--verb phrase
Linking Verb-- Links subject to predicate...the same words as helping verbs, but the linking verb works alone in the sentence--it does not help anything
Ex. She is at the store.-----"is" that's the linking verb in this sentence
