Italian river miles away from wood (5)
I believe the answer is:
tiber
'italian river' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for tiber that I've seen before include "Italian river with Ostia at its mouth" , "River of Rome" , "River entering the Mediterranean at Ostia" , "Rome's river" , "divides Rome" .)
