though

When you use "Though x, y" or "y though x", y is surprising, contrasting, or unimportant. <> kalmar nuna mamaki ko rashin muhimmanci. duk da dai. amma dai.
...even though they think they are doing good things. <> alhali kuwa suna zaton lalle ne su, suna kyautata, (abin da suke gani) aikin ƙwarai = amma suna zaton suna kyautata ayyukan qwarai." --Qur'an 18:104

Though he talked very loudly, she did not hear him.

She did not hear him though he talked very loudly.

There was a real, though small, problem.
When though comes at the end of a clause, it shows it is surprising, contrasting, or unimportant.
That's sound great. It's difficult though.
