In Italian, signore or signor (equivalent to Mr. or sir, depending on the context) can be used together with other titles, for example with dottore ("doctor"), or military ranks (e.g. capitano, "captain").
In particular with the military ranks, there is a difference between Signor Capitano and Capitano. When speaking with other soldiers, Signor Capitano would mean:
- My rank is lower than Captain
- I am speaking with somebody whose rank is higher than mine
Can sir be used with other titles?
What is the equivalent of Signor Capitano, said by someone who has a rank lower than Captain?
To be clear, I am not using sir as title, but as word to respectfully address a man (which is the usage signore has in Italian).
