Please add a "tip" before intruducing family members
There are a lot of similar questions like: "why is there no "il" before mio padre" or "la" before sua figlia.
So if you can, please put that rule regarding singular family members in a tip.
The rule: There is no definite article with possessive that refers to a family member or relative, while in plural form there is.
- Mio fratello / I miei fratelli
- Tuo zio / I tuoi zii
