A clear and concise definition of 'although' for those learning British English.
'Although' is a conjunction used to introduce a contrast or an unexpected outcome. It often connects two clauses, indicating that the second clause presents a situation that is contrary to what might be expected from the first clause. For example, in the sentence 'Although it was raining, we went for a walk,' the use of 'although' shows that the rain was an unexpected reason to not go for a walk, but the action followed regardless.
