From Middle High German zesamene, zesamne, zesamen (“together”), from Old High German zisamane (“together”). From zu- (“to”) + sammen (“together”) (in Modern German, sammen is only found in compounds), from Proto-West Germanic *saman, from Proto-Germanic *samanai (“together”), from Proto-Indo-European *sem- (“together, one”). Cognate with Middle English to-samen (“together”). Related to obsolete English sam (“together”), whose earlier form was samen. Dutch tezamen (“together”) has been formed in a similar fashion, with its contracted form being samen and its ancestral form tsamen. Also cognate with Scots samin (“together”), Danish sammen (“together”), Swedish samman (“together”).
