Last Sunday I did a live Korean classroom about the grammar forms ~더라도 and ~ㄹ지라도. Both of these forms mean "even if," and are different than the regular ~아/어/etc. 도 form (for example, 하다 becoming 해도).
The full live stream lasted over an hour, but the abridged version comes in at just under 8 minutes long. Check it out here~!
