masc nom sg of udāna (noun)
Analysis. ud + ānā: ud (up, out) + ā (toward) + √nā (breathe), literally 'breathing up and out'; an utterance that wells up spontaneously from deep realization.
Etymology. From ud- (up, out) + ā- (toward) + √nā (breathe, < Indo-European *sne- 'breathe, blow'). The spatial imagery is concrete: breath or speech rising upward and outward. Related to English 'nose' (< *sne-) and Latin 'nāre' (swim, originally 'breathe through water'). The term captures utterances emerging unbidden from a Buddha or enlightened being—words that 'breathe forth' spontaneously.
