"Although" and "though" can mean both "but" and "even though". They mean the same thing, but there are two main differences: 1) "Although" is slightly more formal. 2) "Though" can be used at the end of a sentence. 3) "Although" is more commonly used to mean "even though" than "but". E.g. In order from most formal to most informal: "It's raining, although it's still very hot" = "It's raining, though it's still very hot." = "It's raining. It's very hot though." These sentences all mean "It's raining, but it's still very hot". "Although/Though it's raining, it's still very hot" is also possible, but it means something else. Here "although" means "even though". You can always replace "although" with "though" (to make a sentence less colloquial), but you can only replace "though" with "although" if it isn't at the end of a sentence.

'Though' - or more commonly 'even though' - has the same meaning as 'although' when it's at the beginning of a phrase. For example: Although he was ill, he still won the race. Even though he was ill, he still won the race. He still won the race, although he was ill. He still won the race, even though he was ill. Note that 'though' is more flexible than 'although'. One useful function of 'though' is as a kind of 'but' added to the end of a sentence: 'Joe is a bright student. He's lazy, though'.

Okay though mean however. Like: my father driving however my mother haven't driven before. Although mean despite. like: my father driving although he doesn't like to drive. I hope to find it useful.
