In Italian, nona means ninth when used as an ordinal number, referring to something that comes in ninth place. It is the feminine form of nono. For example, you might use it to refer to the ninth item in a list or the ninth day of the month.
Example:
È la nona volta che te lo dico. – It’s the ninth time I’ve told you.
La nona casa sulla destra è la sua. – The ninth house on the right is his.
Additionally, nona can also be a colloquial, shortened form of nonna, which means grandmother. In some Italian dialects or informal settings, people might refer to their grandmother as nona instead of nonna.
Example:
Vado a trovare la mia nona. – I’m going to visit my grandmother.
Both meanings depend on the context in which nona is used
