Here's why:
* Verb phrases are made up of a main verb and any auxiliary verbs that help it.
* Auxiliary verbs include words like:
* be, have, do (used for tenses and other grammatical functions)
* modal verbs (can, could, will, would, may, might, shall, should, must)
Examples:
* Simple: "She walks." (One verb)
* Complex: "They have been playing soccer for hours." (Three verbs: have, been, playing)
* Really complex: "He should have been able to have finished the project by now." (Five verbs: should, have, been, able, finished)
The number of verbs depends on the complexity of the sentence and the desired grammatical structure. The main thing is that the verb phrase works together to convey the intended meaning.
