Hi i was trying to find the meaning of つかなく used in this sentence this is from oregairu ep 11 of the 1st season they are talking about how the line towards the theatre is getting out of hand
あのままだと収拾つかなく なるんじゃねえのか
but since it has more than one meanings i can't seem to decide and also is it possible for verbs ending in ない be conjugated like an i adjective? because i parsed the word as つかない+く conjugation to make it an adverb =つかなく
