A question that occurred to me while asking this one...
동사 (action verbs), 형용사 (adjectives or descriptive verbs), and 이다 (the 'copula') all broadly accept 'verb endings', e.g.
가다 : 갑니다
예쁘다 : 예쁩니다
Is there a word (Korean or English) to collectively describe 'words that you can add verb endings on to'? Maybe I mean something like 'conjugatable'.
