but; although; even though~
Connects two clauses to express a concession: 'but' or 'although', often with a nuance of dissatisfaction or unexpected result.
This pattern is used to say 'although' or 'but', but it carries a feeling that the second clause is unexpected or somewhat disappointing given the first. It is more formal and literary than 'けど' or 'が'. For example, you might say someone studied hard, but still failed the test—there's a sense of irony or regret. In conversation, you will often hear it, but it has a slightly stiff, written tone. It can also be used to politely express disagreement or a counterargument, as in 'although that may be true, I still think...'.
