Nor is 'never forget'. Jesus, this is just pissing me off, from the beginning there wasn't even one sentence without a personal pronoun and now this. The course is still a big mess and can't go through a lesson without getting half of the sentences 'wrong', frustrating as f. Mistakes all over the place
Different types of future tense
(1) -(으)ᄅ 거에요 (Probable future)
결코 잊지 않을게예요 = I will (probably) never forget
The sentence indicates there is some room/a small chance for the situation to change.
(2) Definite Future -(어/아)요 (i.e. the casual, polite present simple tense)
Unlike the probable future, the 요 ending present tense can be used to convey a certain/assured future, when used along with a time reference.
결코 잊지 않아요 I will never forget Time ref: "never".
Regardless, I do not forget =
I (absolutely) do not forget =
절대로 잊지 않아요.
