Railway out from very pleasant city (6)
I believe the answer is:
venice
'city' is the definition.
(Venice is an example)
'railway out from very pleasant' is the wordplay.
I cannot quite understand how this works, but
'very' could be 'v' (abbreviation) and 'v' is found within the answer.
'pleasant' could be 'nice' ('nice' is associated in meaning with 'pleasant') and 'nice' is found within the answer.
A single letter 'e' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for venice that I've seen before include "Grand Canal city" , "Italian city once known as Queen of the Adriatic" , "Archdeacon subject to delay, it's implied, in" , "Old republic" , "Messages" .)
