To surge, swell, or move in waves like the action of tides or heated water; to experience turbulent motion.
From Latin 'aestuare' meaning 'to surge' or 'to seethe,' derived from 'aestus' (tide, agitation). The verb captures the sense of restless, wave-like movement.
This verb describes what water does at high tide—it aestuates back and forth in a powerful, rhythmic dance driven by the moon's gravity.
