Gender of Nouns in Spanish

Overview

Every noun in Spanish has a grammatical gender: it is either masculine or feminine. Unlike English, where gender is mostly biological, Spanish assigns gender to all nouns, including objects, ideas, and abstract concepts. A table (la mesa) is feminine, while a book (el libro) is masculine. This is one of the first things you will learn at the A1 level, and it affects articles, adjectives, and pronouns throughout the language.

The good news is that Spanish has fairly reliable patterns. Most nouns ending in -o are masculine, and most ending in -a are feminine. However, there are notable exceptions that you simply need to memorize. Learning the gender of a noun together with its article from the start will save you a lot of trouble later.

Understanding grammatical gender is not just about getting articles right. It is the foundation for agreement across the entire sentence. Adjectives, demonstratives, and possessives all must match the gender of the noun they describe.

How It Works

General patterns

Ending	Typical Gender	Examples
-o	Masculine	el libro, el gato, el vaso
-a	Feminine	la casa, la mesa, la ventana
-ción, -sión	Feminine	la canción, la televisión
-dad, -tad	Feminine	la ciudad, la libertad
-ma (Greek origin)	Masculine	el problema, el sistema, el tema
-e	Either	el coche (m), la noche (f)
consonant	Either	el reloj (m), la pared (f)

Important exceptions

Noun	Gender	Why it is surprising
el problema	Masculine	Ends in -a but comes from Greek
el día	Masculine	Ends in -a
la mano	Feminine	Ends in -o
la foto	Feminine	Short for la fotografía
la moto	Feminine	Short for la motocicleta
el mapa	Masculine	Ends in -a
el sofá	Masculine	Ends in -a

Nouns for people and animals

For nouns referring to people, gender usually matches the person:

Masculine	Feminine
el profesor	la profesora
el chico	la chica
el alumno	la alumna
el doctor	la doctora

Some nouns use the same form for both genders, changing only the article: el/la estudiante, el/la artista, el/la periodista.

Common Mistakes

Assuming all -a nouns are feminine

• Wrong: La problema es difícil.
• Right: El problema es difícil.
• Why: Words of Greek origin ending in -ma (problema, tema, sistema, programa) are masculine.

Assuming all -o nouns are masculine

• Wrong: El mano está sucia.
• Right: La mano está sucia.
• Why: Mano is one of the rare feminine nouns ending in -o. Always learn it as la mano.

Forgetting gender with abbreviated words

• Wrong: El foto es bonita.
• Right: La foto es bonita.
• Why: Foto is short for fotografía, which is feminine. The abbreviation keeps the original gender.

Not learning the article with the noun

• Wrong: Memorizing mesa without la
• Right: Memorizing la mesa
• Why: If you learn nouns without their articles, you will constantly have to guess the gender. Always study the article as part of the word.

Practice Tips

• Always learn the article with the noun. Instead of memorizing libro, memorize el libro. This makes gender automatic over time.
• Group exceptions together. Make a special list of words like el problema, el día, la mano, and la foto. Review them regularly until they feel natural.
• Color-code your vocabulary. Use one color for masculine nouns and another for feminine. Visual associations help reinforce gender patterns.
