In its simplest form, 라도 attaches to a noun to give it extra nuance or emphasis, like "even [noun] if nothing else" or "even if it is not much", etc. e.g. - 나라도 그렇게 했을 거야 (for subject noun) = I myself would have done the same too (if it had been me). - 이거라도 받아 (object) = Take this (even if it's not much). - 강한 팀이라도 꼭 이긴다는 법은 없다 (subject) = You can't say any team will necessarily win even if they are strong. There are more complex ways -라도 is used, however, combining with other particles or verb forms. Here are examples of it used with other particles. - 친구한테라도 그런 부탁은 못 해 (친구한테(도) emphaized) = You can't ask that kind of favor even to your friend. - 영화관에라도 갈까? (영화관에 nuanced)= Shall we go to the movies (if nothing else)? And here are -라도 used with other verb forms - -더라도, -ㄹ지라도, and other variations. (These are considered separate verb ending forms rather than -라도 varations, but they are closely connected) - 누가 묻더라도 말하면 안 돼 = Don't say it even if someone asks. (묻다 -> 묻더라도) - 내가 죽을지라도 이 일은 꼭 한다 = I will make sure I do this even if that means I'll die. (죽다 -> 죽을지라도) - 그게 사실일지라도 내 생각은 변하지 않는다 = I won't change my mind even if that is true. (사실이다 -> 사실일지라도)
