Anatt1 is the last of the ‘three characteristics’ (ti-lakkha7a) which is according to Buddhism the general characteristics (samañña-lakkha7a) of the universe and everything in it. Like the teaching of the four Noble Truths, it is the teaching peculiar to Buddhas (buddh1nam samukkamsik1 desan1: M I 380). Etymologically, anatt1 consists of the negative prefix an plus att1 (cf. Vedic Sanskrit 1tman). There are two Pali forms of the word, namely, att1 (instr. Attan1) and atta (instr. attena). Neither form seems to be used in the plural in the Tipi5aka.
