## Origin

**Meanings 2, 6, 8–9, 12–13, 16, 19** — The Proto-Indo-European root *webʰ-, meaning to move back and forth or wander, led to Proto-Germanic *wabōną or *wabjaną, meaning "to sway" or "to wander," and to Old English wafian, which meant "to wave, fluctuate, waver in mind." That became Middle English waven. German wabern ("to waft") and Icelandic váfa ("to fluctuate, waver") are related.
**Meanings 1, 3–5, 7, 10–11, 14–15, 17–18** — The Middle English noun *wave has two sources. One is the verb waven ("to fluctuate, wave"). The other is Middle English wawe or waghe, "wave," which came from Old English wǣg ("billow, wave, sea") and goes back through Proto-Germanic *wēgaz ("motion, storm, wave") to Proto-Indo-European *weǵʰ- ("to drag, carry"). German Woge and French vague, a Germanic loan, are cognates.
