Etymology

The word "theoretically" stems from the Greek "theōrētikos" (contemplative, speculative), derived from "theōria" (a looking at, viewing, theory). The suffix "-al" (Latin "-alis") turns the noun "theory" into an adjective, and "-ly" (Old English "-lice") further converts it into an adverb. The progression reflects a shift from abstract observation ("theory") to hypothetical reasoning ("theoretical") and finally to manner of action ("theoretically").
