Though is a word that introduces a contrast or unexpected twist in a sentence. When you say “I studied hard, though I still found the test challenging,” you're acknowledging something that seems to go against what came before. The word signals: “Here comes something that might surprise you given what I just said.”

You can use though at the end of a sentence too: “The weather looked terrible. We went hiking, though.” It adds a note of “despite what you might expect.” This end-position usage feels more casual and conversational.

Though works similarly to “although” and “even though,” but it's shorter and often feels less formal. You might write “Although it was raining, we played outside” in an essay, but say “It was raining. We played outside, though” to a friend.

The word helps you show two things are true at the same time, even when they seem to pull in opposite directions: “She's young, though very wise” or “The book was long, though I couldn't put it down.” It's a way of saying “this is true, and this other thing is also true, surprisingly enough.”
