Noun Gender & Plural Formation

📌 Nota gramatical

In Spanish, nouns that end in the letter -o are generally masculine and take the masculine singular article 'el'. This is one of the most reliable gender patterns in the language.

📌 Nota gramatical

Nouns ending in -a are generally feminine and take the feminine singular article 'la'. This is the counterpart to the -o masculine ending and covers a vast number of everyday concrete vocabulary items.

📌 Nota gramatical

When a noun ends in a consonant, its gender is not as immediately obvious as -o or -a words. However, many nouns ending in -ión, -dad, or -tad are feminine, while others ending in -l, -r, -n, -s, -d, -z tend to vary.

📌 Nota gramatical

Nouns ending in -ista (like turista, dentista) do not change their spelling for gender; only the article changes ('el turista' vs 'la turista'). Similarly, many nouns ending in -e (like estudiante, cliente) use the same form for male and female individuals, changing only the article.

📌 Nota gramatical

To make a noun plural when it ends in an unstressed vowel (a, e, i, o, u) or an accented -á, -é, -ó, simply add the letter -s to the end of the word. The definite article also changes from el/la to los/las.

📌 Nota gramatical

When a noun ends in a consonant (such as l, r, n, d, z, j), you form the plural by adding '-es' to the end. Note that if a word ends in -z, the z changes to c before adding -es (e.g., lápiz becomes lápices).

📌 Nota gramatical

Nouns ending in the letter -z drop the z and add -ces in the plural form. This is a strict phonetic and orthographic rule in Spanish because the letter z never precedes -es in native Spanish spelling.

📌 Nota gramatical

Some singular nouns ending in a consonant carry an accent mark (tilde) to show stress (e.g., 'el bal inscripción', 'el examen' - wait, 'el avión', 'el lápiz'). When these words take '-es' to become plural, the syllable count shifts, and the written accent mark is often dropped because the stress naturally falls on the penultimate syllable.

📌 Nota gramatical

If a singular noun is a compound word or ends in an unstressed vowel plus -s or -x (such as 'el lunes', 'el paraguas', 'el tórax'), the word does not change its form in the plural. Only the article changes to indicate plurality ('los lunes', 'los paraguas').

📌 Nota gramatical

While words ending in -a are normally feminine, words of Greek origin ending in -ma (like problema, idioma, sistema, tema, mapa) are masculine and take the article 'el'.

📌 Nota gramatical

Nouns ending in the suffixes -dad, -tad, and -tud (which correspond to English -ty, -tude) are always feminine and take the article 'la' (e.g., la ciudad, la libertad, la juventud).

📌 Nota gramatical

Some high-frequency human nouns change their root or ending completely to denote gender rather than just changing the article or adding -a (e.g., el hombre / la mujer, el padre / la madre, el actor / la actriz).
