The infinitive — a verbal noun. Learn the tense-aspect forms, the articular infinitive with prepositions (διὰ τό, εἰς τό, ἐν τῷ…), complementary and indirect-statement uses, and the accusative subject. Browse every topic freely; a 90% mastery score still records completion. Cards you grade enter spaced review: the dashboard tells you when they fall due. Progress for this redesigned trainer is saved separately from the archived original.
