'want very much' is the definition.
The definition and answer can be both states of affairs as well as being singular nouns.
Perhaps they are linked in a way I don't understand?

'round the hard master' is the wordplay.
'round' is an insertion indicator.
'the hard' becomes 'h' (abbreviation used in pencil classifications).
'master' becomes 'ace'.
'h' placed inside 'ace' is 'ACHE'.

'to get' is the 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" .)
