The word wound has two unrelated meanings:

1. An injury to the body where the skin is cut, torn, or broken. A wound might be a deep cut from a sharp knife, a scrape from falling off a bike, or a puncture from stepping on a nail. Doctors clean and bandage wounds to prevent infection and help them heal. Serious wounds might need stitches to hold the edges of skin together. The word can also be a verb: a broken bottle might wound someone's hand, or a person might be wounded in battle. People also use wound metaphorically to describe hurt feelings, like when someone's cruel words wound a friend's pride or self-esteem.
2. The past tense of the verb wind (rhymes with “find”). When you wound a clock yesterday, you turned its key to tighten the spring inside. You might have wound a ball of yarn, wrapping it around and around, or wound through a maze, following its twisting path. A movie projector uses film that's wound on reels. Notice that this meaning is pronounced completely differently from the injury meaning, rhyming with “found” instead of “mooned.”
