Morphology

theoretically = theoretical (transparent) = theory + ical + ly

Standard adverb formation from the adjective 'theoretical' yields the meaning 'in a theoretical or principled sense', which learners can derive from the base.

Etymology

The word theoretically comes from theory, which means an 'idea' or a 'plan', so theoretically means 'in principle' rather than in real life. That's why we say something works theoretically when it should be true in idea but may not work in practice.
