Nouns based on biological gender have the same gender as the person to whom they refer. All other nouns have a gender unrelated to their meaning but which can often be determined by the ending. Nouns ending in -o are usually masculine and nouns ending in -a and -i are usually feminine. Nouns ending in a consonant are always masculine as they often come from other languages and are assigned masculine gender. Nouns ending in -e can be either masculine or feminine (although -ie, -trice, -ione and -dine are always feminine); their gender should be memorized.

Here's a menu. The items below are examples of masculine and feminine nouns.
