masc nom sg of sukha (adj)
Etymology. From su- (well, good) + √kha. The root kha relates to space, opening, or ease of movement; su- prefixes the sense of 'well' to create the concrete image of 'moving well, without obstruction'. Cognate with Greek eu- (eu-pnoia 'easy breathing'), Latin suo- (suāvis 'sweet'), and English easy through Indo-European *sweǝ- (dwell, own, one's own). The prefix su- is the same word as Greek eu- (eulogy, Eucharist) and Sanskrit su-, all from the root meaning 'to be good, benefit'.
