Questions & Answers about Il cane ha una coda lunga.
Why is il used before cane, and when should I use lo instead?
Il is the masculine singular definite article used before most consonants. You use il for words like il cane, il libro, il tavolo. You switch to lo when the masculine noun starts with s + consonant (e.g., lo studente), z (e.g., lo zaino), gn/pn (e.g., lo pneumatico), ps (e.g., lo psicologo), x or y (e.g., lo xilofono), or with certain clusters.
How can I tell that cane is masculine and coda is feminine? What are the general rules for noun gender?
In Italian, nouns ending in -o are generally masculine (e.g., il cane, il libro), and those ending in -a are generally feminine (e.g., la coda, la casa). Nouns ending in -e can be either (e.g., il padre vs. la luce) and must be memorized. Since coda ends in -a, it’s feminine; cane ends in -e, but by dictionary it’s masculine.
Why is the indefinite article una used before coda, and what’s the difference between una and un?
