although and though: conjunctions
Both these words can be used as conjunctions, with the same meaning. In
informal speech, though is more common. They introduce an idea (‘A’) with
which the main clause (‘B’) is in contrast. When we say’ (Al)though A, B’, there is something unexpected or surprising about ‘B’.
(Al)though (A) I don’t like him, (B) I agree that he’s a good manager.
(B) I’d quite like to go out, (al)though (AJ it is a bit late.
but and however
We can give the same meaning by putting but or however with the contrasting, ‘unexpected’ clause (‘B’).
(A) I don’t like him, but (B) I agree that he’s a good manager.
(A) I don’t like him. However, (B) I agree that he’s a good manager.
(A) It is a bit late, but (B) I’d quite like to go out.
(A) It is a bit late; however, (B) I’d quite like to go out.
but and however: the difference
But is conjunction: it joins two clauses, and comes at the beginning of the
second. However is an adverb: it does not connect its sentence grammatically to the one before. This is why it comes after a full stop or a semi-colon in the above examples.
However can go in various positions. It is normally separated from its sentence by one or two commas, depending on its position.
However, the police did not believe him.
The police, however, did not believe him.
The police did not believe him, however.
Though used as an adverb
We can use though as an adverb (often at the end of a sentence), to mean
Nice day. ~ Yes. A bit cold, though.
The strongest argument, though, is economic and not political
