It's very simple, Kate. Putting 'though' at the end of a sentence or phrase is the same as putting 'but' at the beginning. It's sunny, today, isn't it? Yes. But it's cold. It's sunny, today, isn't it? Yes. It's cold, though. The meaning is exactly the same.

Though can mean something similar to 'however' and 'although'. Examples: I can't find my shoes. I did find my car keys, though. (= Although I did find my keys, my shoes are still lost.) This seems like a good question, I can't answer it, though. (= It's a good question, I can't answer it, however.) "However" belongs to more formal language, so many people don't use it in so-called everyday speech.

yea u should put it at the end of your phrase when u wanna others believe youor emphesise on what you said or disagree nicely u know?;)) like(i know u dont like it but its good though)
