* "Says" is the third person singular present tense of the verb "to say." So, in a sentence like "She says hello," "says" is definitely a verb.
* However, "says" can also be used as a noun. This is often seen in phrases like "He had his say" or "It's her say-so." Here, "says" refers to the act of speaking or the opinion expressed.
