Doctor given time at the end with a number of Italian royals (8)

'doctor given time at the end with a number of italian royals' is the definition.
I can't tell whether this defines the answer.

'doctor given time at the end with a number' is the wordplay.
'doctor' becomes 'medic' (doctor is a type of medic).
'given' means one lot of letters go next to another.
'at the end' says to take the final letters.
'with' is a charade indicator (letters next to each other).
'number' becomes 'n' (n can represent any number).
The final letter of 'time' is 'e'.
'medic'+'e'+'a'+'n'='MEDICEAN'

Can you help me to learn more?
