pro-verb

In grammar, a pro-verb is a word or phrase that stands in place of a verb (for example, in order that the verb not need to be repeated). It does for a verb what the more widely known pronoun does for a noun. It, along with pronouns and some other word classes, form the general group of word classes pro-forms. It is a type of anaphora. This term is always hyphenated, to distinguish it from the unrelated term proverb.
