Two specialized participial constructions: the genitive absolute (a noun + participle in the genitive, grammatically independent, its own subject) and the periphrastic (εἰμί + participle as a compound verb). Recognize and translate both, distinguish periphrastic from a normal participle, and follow the sentence flow. 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.
