Proto-Japanese: *sa-, *sania
Meaning: 1 a prefix of reciprocal action 2 completely, definitely
Russian meaning: 1 префикс совместного действия 2 совершенно, совсем
Old Japanese: sa- 1, sane 2
Comments: JLTT 515. In some cases the meaning of the prefix is quite uncertain (euphonic?), e. g. sa-wi 'wild boar', sa-jwo 'night' etc.; but with verbs it usually denotes reciprocal or combined action (e. g. sa-ne- 'sleep together', sa-narabe- 'put together on one line' etc.).
