더라

Reporting what you noticed yourself

Passes on something you found out first-hand, by seeing or experiencing it: that foreigners really love Korean convenience stores, that the produce section is near the entrance. The flavour is 'I noticed this', so it does not fit information you merely heard from someone. Stuck onto a question word it becomes digging through your own memory instead — 'how do I do it again?', 'how long have I had this?'. Every line here is plain speech; the polite version is 더라고요.

Register: casual, plain speech
