Convey an image of extremely delicate writer (8)
I believe the answer is:
describe
'convey an image' is the definition.
(describe can mean to convey an image of something)
'extremely delicate writer' is the wordplay.
'extremely' suggests removing the centre (letters on the extremes of the word are used).
'writer' becomes 'scribe' (scribe is a kind of writer).
'delicate' with its middle removed is 'de'.
'de'+'scribe'='DESCRIBE'
'of' acts as a link.
(Other definitions for describe that I've seen before include "Say what something is like (8)" , "Give an account of in words" , "Portray in words" , "Illustrate" , "Give verbal portrait of" .)
