Notes: Mewn cyd-destunau technegol, sylwer bod gwahaniaeth rhwng polling/pôl a voting/pleidleisio. Serch hynny, mewn rhai cyfuniadau hirsefydledig yn Gymraeg defnyddir 'pleidlais' neu 'pleidleisio' i drosi 'poll' neu 'polling', ee polling station/gorsaf bleidleisio, yn enwedig lle mae'r termau hynny yn ymwneud â'r broses o fwrw pleidlais gan unigolyn. Gellir defnyddio'r ffurf ferfenwol 'polio' lle bo angen.
