Irritating way to want fish (8)
I believe the answer is:
needling
'irritating way' is the definition.
'needling' can be an answer for 'irritating'. I'm not certain of the 'way' bit.
'want fish' is the wordplay.
'want' becomes 'need' (needing is a kind of wanting).
'fish' becomes 'ling' (ling is a kind of fish).
'need'+'ling'='NEEDLING'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for needling that I've seen before include "Doing embroidery" , "Provoking or annoying by continual criticism" , "irksome" , "Aggravating" , "Goading or provoking" .)
