해도 돼요

haedo dwaeyo

Is it okay if I…?

When it’s the right choice

해도 돼요haedo dwaeyo is your safe default when the listener’s approval matters: seating, photos, using something, leaving early, adjusting rules. The key idea is permission, not “how to.”

A small cultural note from a moment I remember clearly: at a busy café in Hongdae, I didn’t want to hover with my drink, so I asked a stranger 여기 앉아도 돼요?yeogi anjado dwaeyo? and got a quick nod. That situation is exactly what this form is built for—low-friction permission.

Common trap: learners replace it with 하면 돼요hamyeon dwaeyo because both contain “do,” but the meaning flips from “may I?” to “just do it.” In a workplace, that flip can make you sound like you’re issuing instructions.

Minimal pairs (vs 하면 돼요)

사진 찍어도 돼요?sajin jjigeodo dwaeyo? — Is it okay if I take a photo? 사진 찍으면 돼요? — Is it enough if I take a photo? (odd unless discussing requirements)

하면 돼요

hamyeon dwaeyo

Just do X (that’s enough).

When it’s the right choice

하면 돼요 means “that’s enough / that will do” in the sense of “If you do X, it meets the requirement.” Use it for steps, requirements, and “minimum needed” guidance.
