Etymology

The word "wave" traces back to Old English wafian ("to wave, fluctuate"), likely imitative of the motion itself. It shares roots with Old Norse vafra ("to hover") and German waben ("to weave"). The silent "e" in Modern English preserves the long vowel sound. The core idea of rhythmic motion unites all meanings, from ocean swells to hand gestures.
