1. What Are Nouns in Spanish?

Nouns (sustantivos) are words that name people, places, things, or ideas. In Spanish, every noun has a gender (masculine or feminine) and a number (singular or plural).

2. Gender of Nouns in Spanish

One unique feature of Spanish nouns is that they’re either masculine or feminine.

• Masculine nouns often end in -o (e.g., libro – book)
• Feminine nouns often end in -a (e.g., casa – house)

There are exceptions and rules to help you remember them.

3. Plural Forms of Nouns

Forming plurals in Spanish is simple once you know the rules:

• Add -s to vowels (libros – books)
• Add -es to consonants (mujeres – women)

Some irregular plurals break the pattern.

4. Definite Articles in Spanish

Definite articles (el, la, los, las) work like “the” in English but change according to gender and number.

📚 See full usage rules and examples in Definite Articles in Spanish.

5. Indefinite Articles in Spanish

Indefinite articles (un, una, unos, unas) work like “a” or “some” in English.
They also change based on the noun’s gender and number.

6. Special Case: “Lo” in Spanish

The word lo is unique—it’s not used like el or la.
Instead, it can turn adjectives into nouns (lo bueno – “the good thing”) or serve as a neutral pronoun.
