Puras

Cf. Pū́ras, Puris, Purỹs, Pūrỹs (see). These are surn. of nickname origin, which could be connected with lit. pùrti, pū̃ra „šiauštis, skleistis; darytis puriam, biriam, smulkiam“ (LKŽ X 976) - see also Z. Zinkevičius, 1977, p. 185-186; or perhaps with lit. pūras „purus“ (LKŽ X 947), pū̃ras „žieminis kvietys (Triticum); žieminių kviečių grūdas“ (ibid.) or similar. Cf. still in Latv. Puri, Pūris ¹.
