More eager; comparative form of eager, though less commonly used than 'more eager.'
From 'eager' + comparative suffix '-er,' from Old French 'aigre' meaning sharp or keen. This follows standard English morphology rules for forming comparatives, though modern usage prefers 'more eager.'
English speakers mostly abandoned the '-er' comparative form for 'eager' in favor of 'more eager,' but 'eagerer' technically follows the same rules that give us 'bigger' and 'faster'—showing how inconsistent English comparative forms actually are.
