Sent is the past tense of the verb send, which means to cause something or someone to go from one place to another. When you sent a letter last week, you put it in the mail so it would travel to your friend's house. When your parents sent you to your room, they told you to go there. When a teacher sent an email yesterday, she transmitted it through the internet to reach someone's inbox.

The word appears constantly in everyday life. You might have sent a text message to coordinate meeting up with friends. A coach might have sent a player into the game. A country might have sent astronauts to the Moon. In each case, something or someone moved from here to there because of a deliberate action.

Notice that sent doesn't always mean physical movement. You can send your love to someone far away, or a scary movie might have sent chills down your spine. The core idea stays the same: something travels from one point to another, whether that's a package across town, a message across the internet, or a feeling through your body.
