ㄹ게

Casual 'I'll do it' promise

Commits you to doing something, said to whoever is listening: let me put some on you too, I'll buy it for you, I'll come see it with Seok Sam, Mum will be there soon. It is a promise or a heads-up rather than a neutral prediction, so it only makes sense when there is somebody to hear it. It is plain speech throughout these lines; add 요 for the polite ㄹ게요. Compare ㄹ래, which says what you feel like doing rather than what you undertake to do.

Register: casual, plain speech
