English has two examples of conjugational fusion. There is a copula with an irregular and defective conjugational paradigm. However, they are normally grouped into four classes, based on the conjugational system of Gothic. Finite verbs have three classes of prefixes&colon; modal prefixes, conjugational prefixes, and pronominal/dimensional prefixes. Conjugational endings in Sanskrit convey person, number, and voice. Conjugational endings in Vedic convey person, number, and voice.
