Spanish 1: A Strict Binary

All nouns in Spanish are either masculine or feminine. Usually, nouns ending in 'o' are masculine and those ending in 'a' are feminine. El (the) and un (a) are used for masculine nouns, whereas la and una are used for feminine ones.
Accent marks in Spanish are usually used to denote what syllable/ letter should bear most stress. They're also used to distinguish between homophones.

It's usually possible to omit the pronoun as conjugation usually indicates who does what.
