Proto-Japanese: *sámpúrap-
Meaning: to be hired, serve as samurai
Russian meaning: быть на службе
Old Japanese: saburap-
Middle Japanese: sábúraf-
Tokyo: samurai (n.)
Comments: JLTT 747 (but the assertion that the form with -b- is Heian and later, is wrong; it is certainly attested earlier and precedes the later attested variant samuraf- / sauraf-).
