It is the "yo" conjugation of "comer"--"to eat".
wtf!! facepalm. i don't know how my mind worked 4 days ago to not know this basic conjugation. i guess it really is true that there are some bad and good days when learning languages. sometimes you feel like you already learned a lot, while you feel like you regressed on other days. this is my first time experiencing that dark side of the force lol. (facepalm)
