To swim means to move through water by using your arms, legs, or body. People and animals swim for travel, exercise, play, or survival.
From Old English 'swimman', related to Old Norse 'svimma' and Old High German 'swimman', all meaning 'to swim'. The word is very old and has kept its core meaning.
Swimming is one of the few skills humans can learn that lets us move in a completely different medium than air. For a moment, gravity loses its grip, and your body negotiates with water instead.
