Aišparas

Cf. Áišpore (see). The origin is not entirely clear. Perhaps a derivative of the prefix, where clear- is from *aiž-, and the latter gender can be Lithuanianized from Latv. prefix àiz- „už“ (cf. Ais-pel-kas - see): *Aiz-paras > *Aiž-paras > Ai̇̃š-paras, cf. lit. surn. Ùž-paras Pš. The origin of the second sando -paras is unclear, cf. (?) lit. to pass
