Disgraced master holed up in hut (6)
I believe the answer is:
shamed
'disgraced' is the definition.
(I know that disgraced can be written as shamed)
'master holed up in hut' is the wordplay.
'master' becomes 'M' (common abbreviation eg MA, Master of Art).
'holed' becomes 'a' (I can't justify this - if you can you should give a lot more credence to this answer).
'up' shows that the letters should be reversed in order (in down clue: letters go upwards).
'in' means one lot of letters goes inside another.
'hut' becomes 'shed' (hut in a garden).
'm'+'a'='ma'
'ma' backwards is 'am'.
'am' put inside 'shed' is 'SHAMED'.
Can you help me to learn more?
(Other definitions for shamed that I've seen before include "in disgrace?" , "He's mad (anag)" , "Disgraced or humiliated" , "Made to feel humilated" , "Abashed" .)
