Fathead taking pudding with hesitation (6)
I believe the answer is:
duffer
'fathead' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'pudding with hesitation' is the wordplay.
'pudding' becomes 'duff' (duff is a kind of pudding).
'with' says to put letters next to each other.
'hesitation' becomes 'er' (sound used when hesitating).
'duff'+'er'='DUFFER'
'taking' acts as a link.
Can you help me to learn more?
(Other definitions for duffer that I've seen before include "Useless old fellow" , "rabbit" , "Informally an inefficient person" , "Clot" , "Idiot" .)
