I am studying Russian numbers. The rules are REALLY complex. When I studied много as a numeral, I compared several books, but their explanations differ. 1. Declension i. One says много is NOT declined. ii. Many say it is declined like plural adjectives Nom. мно́го Acc. мно́го Gen. мно́гих Prep. мно́гих Dat. мно́гим Instr. мно́гими iii. One says "Много (or многое, pl. многие) declines both in the singular (Многое было скрыто от меня ‘Much was concealed from me’, Я многому научился у него ‘I learnt a lot from him’) and in the plural..." (Terence Wade's Comprehesive Russian Grammar) 2. In Accusative Case i. Some say regardless of animacy, the accusative is equal to nominative. ii. Some say for inanimate nouns, it is equal to nominative. For animate nouns, it is either nominative or genitive. What should I trust?
