ませんか
(Mase n ka)
won't you...? / would you like to...? (invitation).
Connection rules
- ＋Verb ます-stem + ませんか (the same stem used for the ます form).
- ＋Functionally an invitation, not a literal yes/no question despite the negative shape.
- ＋Compare with 〜ましょうか (shall we) — ましょうか assumes the other party is amenable, while ませんか leaves more room to decline.
