Spanish gender and articles: agreement without guessing
Choose el, la, un and una; form plurals; and learn noun gender through reliable patterns plus high-frequency exceptions.
Spanish nouns have grammatical gender, and articles and adjectives agree with that noun. Learn each noun with its article because endings are clues, not guarantees.
The basic article system
Definite articles are el, la, los, las; indefinite articles are un, una, unos, unas. Agreement tracks grammatical gender and number: el libro rojo, las casas rojas.
Useful patterns and exceptions
Many nouns ending in -o are masculine and -a feminine, but la mano, el día and Greek-derived words such as el problema resist the shortcut. Endings such as -ción, -sión and -dad are commonly feminine.
Why el agua is still feminine
A stressed initial a sound can trigger singular el for ease of pronunciation: el agua fría. The adjective remains feminine and the plural is las aguas.

Should I memorise gender rules?
Use rules to predict, but store every new noun with an article and example.
