But (-지만)

-지만 is a conjunctive ending meaning 'but' or 'however.' It is attached to a verb or adjective stem to introduce a contrast or unexpected result. For example: '비싸지만 맛있어요' (It's expensive but delicious).

This is one of the most straightforward conjunctions in Korean. It works with verbs, adjectives, and 이다 (the copula). You can also use the past tense before -지만: '열심히 공부했지만 시험에 떨어졌어요' (I studied hard but failed the exam).

-지만 is neutral in tone and appropriate in both casual and formal situations. There are other ways to say 'but' in Korean (such as -는데 and 그렇지만), but -지만 is the most direct and commonly taught first. It is essential for making nuanced statements and expressing opinions.
