English visiting very pleasant city (6)
I believe the answer is:
venice
'city' is the definition.
(Venice is an example)
'english visiting very pleasant' is the wordplay.
'english' becomes 'E' (abbreviation).
'visiting' means one lot of letters goes inside another.
'very' becomes 'v' (abbreviation).
'pleasant' becomes 'nice' (associated in meaning).
'v'+'nice'='vnice'
'e' put within 'vnice' is 'VENICE'.
(Other definitions for venice that I've seen before include "Old republic" , "Italian source" , "Wonderful Italian water-city" , "Car free city" , "Italian city with Bridge of Sighs" .)
