Adjetivos de nacionalidad

Spanish nationality adjectives are a small grammar topic with outsized practical importance — español, francés, alemán, marroquí, estadounidense are among the first words any learner will need, and they don't quite behave like other adjectives. Consonant-ending nationalities add -a in the feminine when most consonant-ending adjectives don't. Written accents disappear in the feminine and reappear in odd places. The same word can be the adjective ("Spanish food"), the noun for the person ("a Spaniard"), and the name of the language ("the Spanish language"). And, unlike in English, no nationality adjective is ever capitalized.

This page sorts the nationality system into its three patterns, explains why each pattern looks the way it does, and walks through the spelling traps that catch English speakers.

Three patterns

Every nationality adjective falls into one of three shapes, depending on how it ends in the masculine singular.

1. Four-form — ends in -o in the masculine: mexicano, italiano, sueco. Like other four-form adjectives: -o, -a, -os, -as.
2. Four-form (consonant) — ends in a consonant: español, francés, alemán, inglés. Unlike most consonant adjectives, these add -a in the feminine: española, francesa, alemana, inglesa. Four forms.
3. Two-form — ends in -e, -í, or -a: canadiense, belga, marroquí, estadounidense. One form for both genders, with plural in -s or -es.

Knowing which group a nationality belongs to is everything. Once you have the masculine singular, the rest of the paradigm is mechanical.

Pattern 1: four-form in -o

This is the easiest group — the standard four-form pattern with no surprises. Nationality adjectives ending in -o take -a, -os, -as exactly like any other -o adjective.

Pattern 2: four-form ending in a consonant

This is the pattern that catches every learner. Most consonant-ending Spanish adjectives are two-form — azul, fácil, joven — but nationality adjectives are the systematic exception. They add -a to form the feminine, and that -a triggers an accent shift in the spelling.

The accent dance

Notice the pattern of written accents across the paradigm of francés:

• Masculine singular: francés — accent on the final é.
• Feminine singular: francesa — no accent. The added -a makes the word two syllables long with stress on the penultimate, and Spanish stress rules then mark the stress without an accent.
• Masculine plural: franceses — no accent, for the same reason.
• Feminine plural: francesas — no accent.

In other words, the masculine singular is the only form that needs the accent. The accent appears on francés because the stress falls on the last syllable of a word ending in -s, which Spanish marks with an accent. As soon as you add -a or -es, the stress is on the penultimate syllable of a word ending in a vowel or -s, which is the default and goes unmarked.

The same logic applies to inglés, japonés, holandés, irlandés, escocés, portugués and to the -án group (alemán → alemana, alemanes, alemanas).

The -z → -ces spelling shift

Adjectives ending in -z (andaluz) show the same orthographic change as other -z words: z becomes c before -es. Andaluz → andaluces in the masculine plural, but the feminine adds -a and the z stays — andaluza, andaluzas.

Pattern 3: two-form nationalities

The two-form group covers nationalities whose masculine singular ends in -e, in -í (stressed), or in -a (the -ista-like belga group). These use the same form for both genders.

Ending in -e

Note the ü in nicaragüense — the diaeresis is required so that the gu is pronounced /gw/ rather than /g/. The same dot mark appears in bilingüe, vergüenza, ambigüedad. Omitting it changes the pronunciation entirely.

Ending in -í (stressed)

A small but recognisable group of nationalities ends in stressed -í. These use the same form for both genders, and the plural takes -es — written -íes with the accent preserved (though -ís is also accepted by the RAE in less formal registers).

The accent on -í in the singular is required — it marks the stressed syllable in a word ending in -i (where the default would be penultimate stress). It carries through to the plural in the -íes form because the stress stays on the same syllable.

Ending in -a (the belga group)

A very small set ends in unstressed -a and behaves like the -ista adjectives — invariable for gender, with -s in the plural.

No capital letters

Spanish does not capitalize nationality adjectives, the names of languages, or the inhabitants of a place when these are written in their lowercase noun/adjective form. This is one of the most consistent capitalization differences with English.

The country name (Madrid, España, Francia) keeps its capital because it is a proper noun. The nationality words derived from it (español, alemana, francesa) and the language name (español, alemán, francés) are all lowercase. English speakers find this counterintuitive because English capitalizes Spanish, German, French in every position.

The rule has practical consequences: in any kind of formal Spanish writing — contracts, news, academic prose — a capitalised Español or Francesa outside a sentence-initial position is a real proofreading flag.

Same word, three jobs

A peninsular Spanish nationality word usually does triple duty:

• Adjective: una comida española (a Spanish meal).
• Noun for the person: un español, una española (a Spaniard, male / female).
• Noun for the language: el español (the Spanish language).

For the language, Spanish often uses español and castellano interchangeably in peninsular usage; castellano tends to be preferred in formal or constitutional contexts, español in everyday speech and abroad.

Compared with English

Three differences to internalize:

• English capitalises; Spanish does not. Spanish, French, German → español, francés, alemán. Lowercase always.
• English uses a separate suffix for the noun and the adjective in some cases (a Spaniard vs Spanish music). Spanish uses the same form for both — un español and la música española share the word español/a.
• English has invariable nationality adjectives. Spanish gives them up to four forms. The Spanish woman is la mujer española — both the noun and the adjective have to be feminine.

A note on registers and sensitive terms

Some nationality and ethnic terms have undergone shifts in acceptability that learners should be aware of. Negro/-a in peninsular Spanish remains the standard term for a black person and is broadly neutral in registers from news to literature, though afroamericano is now more common for African Americans and the politically loaded English term has dragged some Spanish writers toward persona negra as a more careful formulation. Gitano/-a (Roma/Romani) is the standard ethnonym in Spain and is not in itself pejorative, though derived expressions (e.g. hacer una gitanería) are.

For nationality adjectives proper — the kind covered on this page — there is no real register variation. Español, francés, alemán, marroquí are all neutral, factual labels used identically in every register.

Common Mistakes

Key Takeaways

• Three patterns: -o four-form (mexicano); consonant four-form with feminine -a (español → española); two-form (canadiense, marroquí, belga).
• Most consonant-ending adjectives are two-form, but nationalities are the systematic exception — they add -a in the feminine.
• The written accent on francés, inglés, alemán is required in the masculine singular only — it disappears in the feminine and plural because the stress no longer falls on the final syllable.
• -í nationalities (marroquí, iraní, israelí) preserve the accent throughout and prefer the plural -íes in careful writing.
• No capitalisation — español, no Español, even when referring to the language.
• One word usually serves three jobs: adjective, person noun, language name (un español, una española, el español).
• The ü in nicaragüense is mandatory — it preserves the /gw/ pronunciation.
