| + | In the [[English language]], the '''base form''' of a [[verb]] functions as the present-[[tense]] form for all [[person (grammar)|persons]] and [[number (grammar)|numbers]]. The exceptions to this are in the case of the third-person singular, which uses the ''-s'' [[affix|suffix]], and in the case of the verb ''to be,'' which is completely irregular. The [[infinitive]] is formed by ''to'' plus the base form. |
