Spanish lesson 1: Nouns, Articles, and Adjectives


The Gender of Nouns and the Definite Article

A noun is a person, place, or thing.
In Spanish, all nouns are either masculine or feminine.

The definite article (the) agrees with the noun in gender and number.

Masculine Singular – Basic Rules

  1. Most nouns ending in -o are masculine: el cuaderno (notebook), el escritorio (desk)
  2. Many end in other letters: el país (country), el profesor (teacher)
  3. Some end in -a or -ma: el mapa (map), el tema (theme)

Feminine Singular – Basic Rules

  1. Most nouns ending in -a are feminine: la playa (beach), la manzana (apple)
  2. Endings -ción, -sión, -dad, -tad, -tud are feminine: la nación, la decisión, la universidad
  3. A few -o endings are feminine: la mano (hand), la radio (radio)
  4. Other endings: la noche (night), la luz (light) – learn with article.

Special Cases: Nouns Ending in -ista or -nte

These can be masculine or feminine; the article indicates the person’s gender.

EndingMasculine (el)Feminine (la)
-istael turista (male tourist)la turista (female tourist)
-nteel dependiente (male clerk)la dependiente (female clerk)

Reminder: Always learn each noun with its definite article (el or la).
