Want very much to get round the hard master (4)
I believe the answer is:
ache
'want very much' is the definition.
'ache' can be an answer for 'want' (I've seen this in another clue). I am unsure of the 'very much' bit.
'round the hard master' is the wordplay.
'round' is an insertion indicator.
'the hard' becomes 'h' (abbreviation used in pencil classifications).
'master' becomes 'ace' (both can mean an expert).
'h' placed inside 'ace' is 'ACHE'.
'to get' acts as a link.
Can you help me to learn more?
(Other definitions for ache that I've seen before include "Feel pain" , "Longing" , "Dull throbbing pain" , "yearning" , "Similar" .)
