〜ませんか is a polite way to invite someone or make a suggestion. It literally means “won’t you…?” and sounds softer than a direct request. Key points: • Verb ません + か makes an invitation • Polite and gentle in tone • Often used with friends or classmates • Similar meaning to “Let’s…?” For example, “一緒に行きませんか” means “Won’t you go together?” or “Would you like to go together?” It sounds friendly and polite. You can use this to invite someone to do an activity: “映画を見ませんか” (Would you like to watch a movie?). This pattern is a question, so the intonation rises at the end. It is very common in everyday conversation when you want to suggest something without sounding too direct. At N5, practice with common verbs like 行きます, 食べます, 勉強します. It will help you make polite invitations easily.
