Questions & Answers about Il suo sguardo è serio.
In Italian, a possessive adjective like suo usually goes together with the definite article, so il suo sguardo is the normal form.
- il = the
- suo = his / her / its / your (formal)
- sguardo = look / gaze
So Italian often says something that is literally closer to the his gaze than to English his gaze.
A very common exception is with some singular family nouns:
- mia madre = my mother
- tuo fratello = your brother
But sguardo is not a family noun, so il suo sguardo is correct.
Suo is a possessive adjective. It can mean:
- his
- her
- its
- your (formal, singular)
So by itself, suo does not tell you whether the owner is male or female. You understand that from context.
For example, il suo sguardo could mean:
- his look
- her look
- your look (when speaking formally)
Italian often leaves this kind of information to context.
