Picture a flag snapping, a candle flame trembling, or a sailor’s hand moving uncertainly in the air: all belong to the same old family of motion. The trail reaches back to Proto-Indo-European *webʰ-, “to braid or weave,” a root that also produced English weave and web—language preserving the idea of strands moving in and out. Old Norse vafra meant “to move unsteadily” or “flicker,” while Middle English waveren, recorded by the 14th century, extended that physical wobble to people who could not settle on a decision. English then added the frequentative suffix -er, giving repeated or restless motion: not one decisive swing, but a continual back-and-forth. So when someone wavers, their mind is metaphorically weaving—crossing and recrossing the same two possibilities like threads that refuse to lie still.
