"This person eats bread."
Translation:Этот человек ест хлеб.
When do I use этот instead of это?
Note/Edit: I know that эта is for feminine words.
Is there any system to the way gender is attributed to nouns? Meaning, is there a way to figure it out without knowing, or is it just something you have to memorize when you learn new vocabulary?
There are some rules of thumb: feminine nouns mostly end in "а", "я", masculine in a consonant, neuter in "о", "е", "мя". But of course there are exceptions to this rule. Nouns that name people or animals have gender of a person/animal they name: дядя (uncle) is masculine. And also there are a quite a few feminine nouns that end in "ь"
