Комментарии:JLTT 751. The accent in RJ and PJ is exceptional, showing that the word is treated as a compound *sí- 'make' + *mi-as- 'show, cause to see'. One may suppose that original *sìmà-s- (causative from the attested *sìmà-, OJ sìmà-, Tokyo shimé- "mark, mark out as one's territory") was restructured under the influence of *mì-as- 'show'.
