Verbs. And verbs are a very important, in fact, a very necessary part of speech because verbs are needed in every single sentence. Without a verb, you have what’s called a sentence fragment. As you can see here, “All the nurses at the seminar.” Well, there’s no action in that sentence. Right? This idea is not complete. It’s not clear what is actually happening in this sentence, so you need to add some sort of verb. For example, “All the nurses were at the seminar.” or “All the nurses attended the seminar.” I’m not going to read through these other sample sentences down here, but you can see in these sentences the verbs are highlighted in blue and you can see that all of them do indeed include verbs.
