In grammar, the comitative case (abbr. com) is a grammatical case that denotes accompaniment.[1]: 17–23 In English, the preposition "with", in the sense of "in company with" or "together with", plays a substantially similar role. Other uses of "with", like in the meaning of "using" or "by means of" (I cut bread with a knife), correspond to the instrumental case or related cases.
