Etymology
The word 'theoretically' is built upon the Greek noun theōria, meaning 'contemplation' or 'speculation', which itself derives from the verb theōrein ('to look at, observe'). The adjectival form theōrētikos entered Late Latin as theoreticus, giving rise to the English adjective 'theoretic' or 'theoretical'. The adverbial suffix '-ally' is a double suffix, historically combining the Latin adjectival '-ālis' with the adverbial '-iter', which evolved into the ubiquitous English '-ly' through Germanic influence. Thus, 'theoretically' literally means 'in a manner pertaining to contemplation or speculation', evolving from its ancient sense of detached observation to its modern meanings concerning abstract principles and hypothetical scenarios.
Analysis
theoretic: From Greek theōrētikos (contemplative, speculative), via Latin theoreticus. It functions as the adjectival base. ally: A suffix forming adverbs from adjectives, of Latin origin (-ālis + -iter), via Old French -el + Middle English -ly.
