Guided lesson
Telling the hour: the је/су switch
Ten minutes on the topic's central quirk: сат follows the same 1 / 2–4 / 5+ counting rule as any other noun, but the verb does something asymmetric - 2–4 pairs with plural су, while 1 and 5+ both pair with singular је, even though 5+ is semantically plural. Build sentences naming an exact hour before choosing and translating your way through the rest.
