If something is sculpted, it's carved or modeled into a deliberate shape. An artist might make a sculpted statue of a Greek god.
You can use the adjective sculpted to describe anything that's been shaped into a specific form, whether it's a sculptor's block of clay or a wood carver's tree trunk, sculpted into the shape of a lighthouse. People use the word to describe human bodies, too — your brother might go to the gym every day with the hope of getting sculpted abdominal muscles, for example. The Latin root sculpt means "to carve."
