You can exchange 'though' for however. * This is a good question. I don't know the answer, though. = However, I don't know the answer. You can also say that using "though" at the end of a sentence is like using 'but' at the beginning. * I'd like to go out for dinner. It's raining, though. = I'd like to go out for dinner, but it's raining.

it generally use to change the sentence in opposite ( ironic) direction. ex: it is rainy day though road are not wet. I wear beautiful dress today though my friend does not compliment on me.

It can be used a couple of ways: 1, a man says to you "I want five apples" and you say "I only have three though" therefore you are using it almost as a restriction. 2, "though the woman only had three apples she gave the man two" an alternative would be "despite the fact that the woman had three apples... "
