Express a view having little work in Evans Head (5)
I believe the answer is:
opine
'express a view' is the definition.
(I've seen this in another clue)
'little work in evans head' is the wordplay.
'little work' becomes 'op'.
'head' says to take the initial letters.
The initial letter of 'evans' is 'e'.
'op'+'in'+'e'='OPINE'
'having' is the link.
(Other definitions for opine that I've seen before include "Consider" , "Express one's opinion openly" , "Think - express a view" , "Express a point of view" , "Give one's view" .)
