'Chī fàn' literally combines 吃 (chī), meaning 'to eat', and 饭 (fàn), meaning 'cooked rice' or more broadly 'a meal'. Together, the phrase means 'to eat (a meal)'—not just rice, but breakfast, lunch, or dinner in everyday contexts. It’s a fundamental verb phrase used across all registers, from casual family talk to formal invitations.

Unlike English 'to eat', which can refer to any food consumption, 'chī fàn' specifically implies sitting down for a proper, usually cooked, meal—often shared with others. It rarely describes snacking or eating on the go; for those, speakers use phrases like '吃点东西' (chī diǎn dōngxi, 'eat something') or '吃零食' (chī língshí, 'eat snacks'). The phrase is also commonly used idiomatically in invitations ('Nǐ chī fàn le ma?' — 'Have you eaten?') as a polite greeting equivalent to 'How are you?'
