This article tries to interpret the word Nigada in a new way. So far Nigada has, on the basis of medieval commentaries, been identified with praia or sampraia, or it has been understood as a term which includes both concepts. As Vedic ritual literature hardly provides an explanation of this word, examples of the use of Nigada have been collected and analysed here. This lead to the conclusion that Nigada is a prose mantra which can be distinguished from sampraia, praia, and nivid. At various occasions during a sacrifice, and because of various reasons, a Nigada is spoken (mostly) by the hot, as an injunction directed to the priests as well as to the deities.
