Possibly from Proto-Indo-European *sm̥-meh₁lom (“one time”, literally “one-measure”), from *sem- (“together, whole, one”) and *meh₁-lo- (“measure, time”) (compare Proto-Germanic *mēlą), from *meh₁- (“to measure”). See each for cognate words. However, this is uncertain and would involve some phonetic irregularity. This etymology is incomplete. You can help Wiktionary by elaborating on the origins of this term.
