This past Sunday I taught a live Korean class all about the grammar form (으)려면, which is a shortened version of the grammar (으)려고 하면.
(으)려면 is used to mean "If you want to." However, it's different than just using ~고 싶으면 or ~고 싶다면, which literally also mean "If you want to." We discuss how it's different in this live stream.
Also in addition to (으)려면, you might see (을/ㄹ)려면 and (을/ㄹ)라면, which are alternate versions of this grammar form - although they're both incorrect grammar.
