Sanskrit <sima'> "all, every, whole, entire" seems to be related to the *sem-/som-/sm- root with a fundamental meaning "one". But can anyone tell me why Sanskrit has <i> in this word? If it is from *smmo- one would expect <sama'>, would one not? There doesn't seem to be evidence of a laryngeal from other IE languages, so why the <i>? Anyone?
