Etymology Origin:
The word "finally" evolved from the Latin finis (meaning "end"), which passed into Old French as final and later into Middle English. The suffix -ly was added to form an adverb, emphasizing the conclusive nature of an action or event. The progression reflects a logical shift from spatial/temporal boundaries (Latin finis) to abstract conclusions (modern "finally").
