Etymology
the verb 'waver' originates from the middle english 'waveren', a frequentative form of the old english 'wafian', meaning 'to wave, fluctuate'. the frequentative suffix '-er' (as seen in verbs like 'flicker' from 'flick') implies a repeated or back-and-forth action. this etymological construction directly informs its modern meanings: the core sense of repeated, unsteady motion evolved metaphorically to describe hesitation in thought or decision. thus, the literal act of waving back and forth became the abstract concept of mental vacillation.
Analysis
