They don't travel overland from San Remo (7)
I believe the answer is:
oarsmen
'they don't travel overland' is the definition.
The definition suggests an adverb but the answer is not.
'from san remo' is the wordplay.
'from' is an anagram indicator (from the letters).
'san'+'remo'='sanremo'
'sanremo' anagrammed gives 'OARSMEN'.
Can you help me to learn more?
(Other definitions for oarsmen that I've seen before include "They row the boat" , "A sermon about rowers" , "Male propellers of boats" , "Male rowers" , "Strokes" .)
