Section 3.3 · Nationalities function as adjectives in Spanish — they must agree in gender and number with the person or object they describe
Nationalities in Spanish function as adjectives. This means they must follow the rules of gender and number agreement you learned in Chapter 2. They must match the person or object they are describing.
In this section you will learn three distinct patterns for nationality adjectives — those ending in -o, those ending in a consonant, and those ending in -ense — as well as the important capitalization rule and two equivalent ways to express national origin.
| Pattern | Masc. Sg. | Fem. Sg. | Masc. Pl. | Fem. Pl. | Example |
|---|---|---|---|---|---|
| Ends in -o | -o | -a | -os | -as | mexicano / mexicana / mexicanos / mexicanas |
| Ends in consonant | base form | +a | +es | +as | inglés / inglesa / ingleses / inglesas |
| Ends in -ense | -ense | -ense | -enses | -enses | canadiense / canadiense / canadienses / canadienses |
| Capitalization | Never capitalized (unless starting a sentence) | mexicano, colombiana, inglés, canadiense | |||
| SER + de vs. adjective | Both forms are correct and interchangeable | Es de Colombia. = Es colombiana. | |||
For nationalities that end in -o, you change the ending to -a for females, -os for a group of males or a mixed group, and -as for a group of all females. This is the most common pattern and mirrors the standard -o adjective agreement rule from Chapter 2. Common nationalities in this group include mexicano, americano, colombiano, cubano, chileno, guatemalteco, dominicano, peruano, venezolano, and italiano.
If a nationality ends in a consonant, it is usually masculine by default. To make it feminine, you simply add an -a to the end. Note that the accent mark is often dropped in the feminine and plural forms because adding a syllable shifts the natural stress. For example: alemán → alemana (the accent on á is no longer needed because the stress naturally falls on the correct syllable). Common nationalities in this group include inglés, francés, alemán, japonés, portugués, danés.
Nationalities that end in -ense (like estadounidense or canadiense) are gender-neutral. The word stays the same whether you are describing a man or a woman. You only add an -s for the plural form. This mirrors the gender-neutral adjective rule from Section 2.1 — adjectives ending in -e have only two forms: singular and plural. Common nationalities in this group include estadounidense, canadiense, costarricense, nicaragüense, londinense.
Unlike in English, nationalities and languages are not capitalized in Spanish unless they start a sentence. This is one of the most common writing mistakes for English speakers. In English you write "She is Mexican" and "He speaks French" — both capitalized. In Spanish: Ella es mexicana and Él habla francés — both lowercase. The same rule applies to languages used as nouns: el español, el inglés, el francés are all written in lowercase when they appear mid-sentence.
You have two ways to express origin in Spanish. You can use the preposition de followed by the name of the country, or you can use the nationality adjective directly. Both are correct and very common in everyday conversation. The de + country construction is often more versatile when you want to specify a region or city rather than a whole country: Ella es de Bogotá. The adjective form can feel more personal or identity-focused: Ella es colombiana.
| Using SER + de + Country | Using Nationality Adjective |
|---|---|
| Usted es de los Estados Unidos. | Usted es estadounidense. |
| Ella es de Colombia. | Ella es colombiana. |
| Nosotros somos de El Salvador. | Nosotros somos salvadoreños. |
Study each nationality in both its masculine and feminine forms. Note which pattern each one follows — this tells you how to form all four agreement forms.
| Country | Masculine Singular | Feminine Singular | English | Pattern |
|---|---|---|---|---|
| Estados Unidos | Estadounidense | Estadounidense | American / US Citizen | -ense |
| México | Mexicano | Mexicana | Mexican | -o ending |
| Colombia | Colombiano | Colombiana | Colombian | -o ending |
| El Salvador | Salvadoreño | Salvadoreña | Salvadoran | -o ending |
| Canadá | Canadiense | Canadiense | Canadian | -ense |
| Italia | Italiano | Italiana | Italian | -o ending |
Listen to each sentence in Spanish, then repeat it aloud during the countdown pause.
Each sentence below uses a nationality adjective in a natural, everyday context. As you listen, identify which pattern the nationality follows — -o (four forms), consonant (+a for feminine), or -ense (gender-neutral). Notice whether the nationality agrees with its noun in gender and number, and confirm that it is not capitalized.
Step 1 — Listen: The Spanish sentence plays automatically. Focus on the nationality word — what is its ending? Does it agree with the noun it describes?
Step 2 — Repeat: During the 4-second countdown, say the sentence aloud — pay special attention to the nationality's ending and its position after the noun.
Step 3 — Adjust: Use the Speed and Volume sliders to find your ideal practice pace.
Name the pattern: After each sentence, silently label the nationality's pattern — "-o ending," "consonant ending," or "-ense." This builds the reflex to produce the correct form automatically.
Watch for accent changes: In sentences 6–10, listen carefully for consonant-ending nationalities and notice how the feminine and plural forms drop the accent mark.
Compare both origin forms: Sentences 21–25 pair SER + de with the equivalent nationality adjective. Practice both forms — fluent speakers use both interchangeably.
