Noun Gender & Plural Formation

📌 Nota gramatical

In Portuguese, grammatical gender is fundamental. Most nouns ending in '-o' are masculine. To form the definite singular, use 'o' (the). Examples include everyday concrete objects and people.

📌 Nota gramatical

Counterpart to the -o ending, nouns ending in '-a' are predominantly feminine, requiring the definite article 'a' (the). This includes many common everyday objects and professions.

📌 Nota gramatical

For animate nouns (people and pets), the masculine ending '-o' shifts directly to '-a' to indicate a female referent, maintaining the root stem of the word.

📌 Nota gramatical

Nouns ending in '-or' add '-a' to form the feminine (e.g., professor -> professora). However, nouns ending in '-ista' (like artista, turista) do not change their ending; gender is shown only by the article (o turista / a turista).

📌 Nota gramatical

The simplest plural rule in Portuguese: if a noun ends in a vowel (a, e, i, o, u) or a diphthong, simply append '-s' to the end of the word. Articles and adjectives must also agree.

📌 Nota gramatical

When a noun ends in the nasal consonant '-m', drop the '-m' entirely and replace it with '-ns'. The nasal sound shifts accordingly (e.g., homem becomes homens).

📌 Nota gramatical

The ending '-ão' is notorious in Portuguese because it has three possible plurals (-ões, -ães, -ãos). The most common pattern by far for everyday A1 vocabulary is shifting '-ão' to '-ões'.

📌 Nota gramatical

A subgroup of '-ão' nouns forms its plural by simply adding an '-s' to the singular form, resulting in '-ãos'. Examples include family relations and monosyllabic words like cão (dog).

📌 Nota gramatical

When a noun ends in a lateral '-l' preceded by a vowel (al, el, ol, ul), drop the '-l' and add '-is'. Note that in European Portuguese, this changes the vowel sound pronunciation (e.g., animal -> animais).

📌 Nota gramatical

For nouns ending in '-il': if the stress is on the final syllable (funil), drop the '-l' and add '-is' (funis). If the stress is on the penultimate syllable (fácil), drop the '-l' and add '-eis' (fáceis).

📌 Nota gramatical

When a noun ends in an unstressed '-s' (or '-x'), its spelling remains identical in the plural. Plurality is indicated exclusively by the article or modifying adjectives (o lápis -> os lápis).

📌 Nota gramatical

Some high-frequency A1 nouns do not follow standard rules. For example, o pai (father) becomes os pais (parents/fathers). Always memorize the plural form alongside the singular for high-frequency survival words.
