먹으세요

meo-geu-se-yo · literally “Please eat”

Situation: Inviting your grandmother or your boss to start eating: 'Please enjoy your meal.'

✕ What AI tells you

Builds the honorific by adding -(으)세요 to the basic verb: '할머니, 먹으세요' or '맛있게 먹으세요'.

Why it fails: For a handful of everyday verbs, Korean uses a completely different word for respected people. 먹으세요 to an elder sounds like a grammar exercise and can come across as impolite.

Cultural nuance, in depth

Most Korean verbs become honorific by adding -시-, which is why learners (and AI) apply the rule everywhere. But the most frequent actions in daily life — eating, sleeping, being somewhere, speaking — have their own respectful vocabulary, and those are exactly the words you use with elders every day. Using the special verb shows you see the person as someone to honor, not just someone to be polite to. Note the split for 있다: 계시다 for a person being somewhere, but 있으시다 for possessions (시간 있으세요?).
