Questions & Answers about La voce di mia madre mi tranquillizza quando ho paura.
Because voce is a singular feminine noun, and in Italian common nouns usually need a definite or indefinite article.
- la voce = the voice
- una voce = a voice
So La voce di mia madre means the voice of my mother / my mother’s voice.
In Italian, family members in the singular usually appear without an article when they are used with a possessive adjective.
So:
- mia madre = my mother
- mio padre = my father
- mia sorella = my sister
and not normally:
- la voce della mia madre
The version with della mia madre sounds unusual here and would only appear in special contexts.
