그든

Sloppy spelling of -거든, 'you see'

그든 is -거든 as it comes out in fast, careless speech: it hands the listener a piece of background they did not have. 나도 봉화에 가본 적은 없그든 'I've never been to Bonghwa either, see.' With a rising tone it invites the listener to take it in and wait for the point — 2시간 딱 되그든? 'we've got exactly two hours, right?' The same ending also appears spelled 거등.

Register: very casual speech
