"If I were you" statements in Korean
Is there a grammar pattern for creating statements like
"If I were you, I would do _____"
"If I were him, I wouldn't ______"
"If I were you, I would have done ______"
...?

I feel like there has to be some sort of grammar pattern for this because just using literal translation is clunky and seems really incorrect ...
"난 너 라면, ____ 했을거야 " ....?? Feels weird / incorrect to me...

Any help would be great :-)

Answer

"If I were you, I would do _____"      "만약 내가 너라면, _____ 할거야."
"If I were him, I wouldn't ______"      "만약 내가 그라면, _____ 하지않을거야."
"If I were you, I would have done ______"     "만약 내가 너라면, _____ 했을거야."

If = 만약

Answer

You can do it much efficienter. "나라면" (roughly "if it was me")
