Listening is learning. So here we go:

Though: I am a vegetarian

, even THOUGH I was in the military.
Thought: I never thought I would be sad.
Through: But, I got through it!
Throughout: Throughout the whole journey, I knew it would turn out well.
Thorough: To speak fluently, you have to be thorough, study and practice everything!
Tough: It's tough and you have to be tough.
Taught. Wow! You taught yourself so much!
