Pinas

Cf. still in Latv. Pinne ¹, Pinnis ², lit. Pinus ³. The origin is not entirely clear. The prevalence of the surname would suggest that it is borrowed from the Latvian surn. But cf. lit. pi̇̀nas „statiniais pintos tvoros pagalys, šaka, lazda; žiogris, pinutis and others“, pi̇̀nas „išdykėlis, paikšas“ (LKŽ IX 1035). See also Z. Zinkevičius, 1977, p. 182.
