"Heal" is one of those words that seems simple until you look underneath. Today it means to make or become sound or healthy again. But its origins tell a richer story.
From Old English 'hǣlan' (to make whole), from Proto-Germanic *hailjaną, from *hailaz (whole, healthy). Same root gives 'health,' 'whole,' and 'holy.' The word entered English around c. 700, arriving from Old English.
