Common questions
Why are Korean particles so hard for English speakers?
Because English marks the same distinctions with word order and does not mark others at all. There is no English slot corresponding to 은/는, so there is nothing to translate it into — which is why a definition alone never settles the question and a side-by-side comparison does.
Which particle pair should I sort out first?
은/는 versus 이/가, by a distance. It appears in the first sentence you ever build and stays wrong for years if it is learned as "they're both subject markers". 에 versus 에서 is the next one, and is much easier — the verb decides it.
