Old Roman I upset touring capital of Italy at first (7)
I believe the answer is:
initial
'first' is the definition.
(similar in meaning)
'old roman i upset touring capital of italy' is the wordplay.
'old roman' becomes 'latin' (I am not sure about the 'old' bit.).
'upset' says the letters should be written backwards.
'touring' means one lot of letters goes inside another (tour can mean to go around).
'capital of' indicates taking the first letters.
The first letter of 'italy' is 'i'.
'latin'+'i'='latini'
'latini' back-to-front is 'inital'.
'inital' placed around 'i' is 'INITIAL'.
'at' is the link.
Can you help me to learn more?
(Other definitions for initial that I've seen before include "Sign" , "Occurring at the beginnng" , "Start of name" , "write two or three letters, usually" , "Primary" .)
