pro-verb

In linguistics, a pro-verb is a word or partial phrase that substitutes for a contextually recognizable verb phrase (via a process known as grammatical gapping), obviating the need to repeat an antecedent verb phrase. A pro-verb is a type of anaphora that falls within the general group of word classes called pro-forms (pro-verb is an analog of the pronoun that applies to verbs instead of nouns). Many languages use a replacement verb as a pro-verb to avoid repetition: English "do" (for example, "I like pie, and so does he"), , .

The parallels between the roles of pronouns and pro-verbs on language are "striking": both are anaphoric and coreferential, able to replace very complex syntactic structures. The latter property makes it sometimes impossible to replace a pro-verb with a verb, thus its utility (like the one of a pronoun) goes beyond the stylistic variation of word substitution. When choosing between substituting a pro-verb and repeating a verb, in multiple languages, including English, French, and Swedish the repetition is preferred by a wide margin (up to 80% to 20% ratio in the modern French). In many cases this is due to the presence of different objects, like in "I will read your letter every day, as a Christian reads the Gospels". Chance of using a pro-verb increases as the complexity of the verb phrase being replaced grows; verbs in the passive voice have lower chance of being substituted by a pro-verb.
