    When forming the plural of nouns ending in a consonant, such as words of foreign origin, only the article changes: il film/i film; la photo/le photo. Here are some exceptions to the rule for forming feminine plurals:
    Feminine-noun ending -ea changes to -ee in the plural. For example: dea/dee (goddess/goddesses).
    Feminine-noun ending -ca changes to -che in the plural. For example: amica/amiche (friend/friends). Remember that -che is pronounced as "keh" in Italian.
    Finally, be aware that some nouns end in -e. The plural forms of these nouns will end in -i (regardless of whether these nouns are masculine or feminine).
