'BUT' in Korean. 1. 그렇지만, 하지만 => used in the beginning of a sentence for an emphatic "but" or "however". 2. ~지만 => verb (connective) conjugation for "but" or "even though". * You can think of 하지만 as a special case of ~지만. 하다 often stands in for other verbs - in this case, 하다 is a shorthand for what was just said. Since ~지만 means "but", "even though" or "still", 하지만's exact meaning is "That's true, however ...". 3. 그러나, 하나 => Similar to 그렇지만 and 하지만. 4. ~(으)나 => similar to ~지만. (Again 그러나 and 하나 are special cases of ~(으)나. ~(으)나 has a literary feel) Examples: - 날씨는 맑아요. 하지만[그렇지만, 그러나] 바람이 불어요. (It's [The weather is] clear. But the wind blows.) - 날씨는 맑지만 [맑으나] 바람이 불어요. (It's clear but the wind blows.) - 월요일이었다. 그렇지만[하지만, 그러나] 그는 출근하지 않았다. (It was Monday. But he didn't show up at work.) - 월요일이었지만 [일요일이었으나] 그는 출근하지 않았다. (It was Monday but he didn't show up at work.) In terms of their meanings, ~(으)나 is closer to "but" while ~지만 is more like "even though". But ~(으)나 sounds literary and is not used that much in speech, so ~지만 is probably the best phrase for "but" overall.
