이 사랑이 죄일지라도 멈추지 않아

The line, explained

Korean has a ladder of 'even if' endings and you have climbed most of it: -아/어도 for everyday concessions, -더라도 for stronger, more hypothetical ones. At the top sits -(으)ㄹ지라도. It is the version you would carve into a ring. It belongs to lyrics, speeches and historical dramas, and when a title track reaches for it, the song is announcing that it means business. Today's line is a textbook case: a love, a sin, and a refusal.

이 사랑이 is 이, 'this', 사랑, 'love', and the subject marker 이. Simple, but note that 이 사랑 (this love) rather than 내 사랑 (my love) frames the feeling as a thing in the room, almost a third character. 죄일지라도 is 죄, 'sin, crime, guilt', plus the copula 이다, plus -(으)ㄹ지라도. The stem 이- ends in a vowel, so the ending is -ㄹ지라도: 죄일지라도, 'even if it be a sin'. The English 'be' is deliberate; the Korean carries the same old-fashioned subjunctive tone.

멈추지 않아 is 멈추다, 'to stop, to come to a halt', in the long negative -지 않다, conjugated casually: 'I do not stop'. Korean needs no future marker here; the bare present after a concession reads as 'I will not'. The two halves are built to clash. One is heavy, literary, almost liturgical; the other is flat, casual, four syllables. That clash is the sound of someone who has considered the gravest objection and answered with a shrug.

Why is -(으)ㄹ지라도 more solemn than -더라도? Partly history: -지라도 descends from older literary Korean and still appears in translated scripture and classical poetry, so it carries that echo. Partly use: Koreans simply do not say it in conversation. 비가 올지라도 갈게 would make a friend laugh. In a chorus, though, that distance from ordinary speech is a gift. It lets the singer sound like they are swearing on something, and it stretches well over a long melodic note because 지라도 has three open syllables.

Swap the noun and watch the register hold. 이 사랑이 꿈일지라도 (even if this love is a dream), 독일지라도 (even if it is poison), 거짓일지라도 (even if it is a lie). Each stays at the same lofty height, and the refusal after it stays stubbornly plain. When you hear -(으)ㄹ지라도 in a song from now on, listen for that structure: a grand condition, then a short, unshakable answer. It is one of the oldest shapes in Korean lyric writing, and now you know what it is called.
