aux: auxiliary

An auxiliary of a clause is a non-main verb of the clause, e.g., a modal auxiliary, or a form of be, do or have in a periphrastic tense.

(Contrary to the older SD and arguments of Pullum (1982) and following, infinitive to is not analyzed as an auxiliary. Instead, it is analyzed as a mark.)
