Questions & Answers about Σήμερα δεν καταλαβαίνω καθόλου αυτή τη λέξη.
Greek often drops subject pronouns because the verb ending already shows the person/number.
καταλαβαίνω = I understand (1st person singular), so εγώ (I) is optional. You might add εγώ only for emphasis or contrast.
δεν is the basic negation word for many verb tenses (including the present). It normally comes directly before the verb phrase:
δεν καταλαβαίνω = I don’t understand.
(You’ll also see μη(ν) in other contexts, like commands/subjunctive.)
In Greek, this combination is standard and not considered “illogical.”
δεν negates the verb, and καθόλου strengthens it: not … at all / not in the slightest.
So δεν καταλαβαίνω καθόλου is a very natural way to say I don’t understand at all.
