So for example, if I'm speaking in English, I have to speak grammatically differently if I'm talking about past rain, "It rained yesterday," current rain, "It is raining now," or future rain, "It will rain tomorrow."
De pildă, dacă vorbesc engleză, trebuie să folosesc reguli gramaticale diferite dacă vorbesc despre trecut: „Ieri a plouat”, prezent: „Acum plouă”, sau viitor: „Mâine va ploua”.
