osnadh

a sigh, so Irish, Old Irish osnad, Welsh uchenaid, uch, Breton huanad. Zimmer has analysed this into os, up, and an (root of anail), breat: "up-breath"; cf. Latin suspirium, from sup-spírium, "up-breath". But consider *ok-s, from uk of och. Cf. Early Irish esnad, Middle Irish easnadh, song, moaning.
