Grammatical Features

Gender and Article Agreement

• Feminine nouns that start with i are common, especially those ending in -a (e.g., idea, isla, imagen, inversión).
• Masculine nouns often end in a consonant (e.g., instrumento, insecto, inicio, iridio, inventario).
• When the noun begins with a stressed i followed by a vowel (e.g., idea), the article contracts to la (la idea).

Plural Formation

• Most nouns add -es to form the plural (e.g., las ideas, las islas, los instrumentos).
• Exceptions include nouns ending in -z (e.g., los idiomas → los idiomas stays the same) and those ending in -s already (e.g., los iris → los iris).

Accentuation

• Nouns that carry the stress on the penultimate syllable and end in a vowel, -n, or -s require an accent mark (e.g., ínicio, ínsecto).
• The vowel i itself rarely carries an accent unless it breaks a diphthong (e.g., íntimo).
