Spooner kept stuff from angry milliner (3,6)
I believe the answer is:
mad hatter
'spooner kept stuff' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'angry milliner' is the wordplay.
'angry' becomes 'mad' (similar in meaning).
'milliner' becomes 'hatter' (synonyms).
'mad'+'hatter'='MAD HATTER'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for mad hatter that I've seen before include "Crazy man" , "Participant in the 16 in 3,8" , "One at party" , "one forever taking tea" , "Participant in party in Wonderland" .)
