Progressiv (-고 있다)

Using -고 있다 with adjectives. Not distinguishing ongoing action from resulting state. Overusing progressive where simple present suffices. EN speakers: May overuse progressive as in English ('I'm living in Seoul' → Korean prefers 서울에 살아요, not 살고 있어요). Also forget it can't be used with adjectives. DE speakers: German has no progressive — uses simple present for ongoing actions ('Ich esse gerade'). Need to learn when Korean requires the progressive form. RU speakers: Russian uses imperfective aspect for ongoing actions, not a separate progressive. Mapping imperfective → -고 있다 works sometimes but not always. CS speakers: Czech uses imperfective verbs similarly to Russian. The dedicated progressive form is a new concept.
