.... cushion. Dorothy ends in ricefield (5)
I believe the answer is:
paddy
'ricefield' is the definition.
I can't judge whether this definition defines the answer.
'cushion dorothy ends' is the wordplay.
'cushion' becomes 'pad' (to cushion something is to pad it).
'ends' suggests removing the centre.
'dorothy' with its centre taken out is 'dy'.
'pad'+'dy'='PADDY'
'in' is the link.
Can you help me to learn more?
(Other definitions for paddy that I've seen before include "show of anger" , "Sort of wagon" , "One regularly flooded" , "Wobbly" , "Temper tantrum" .)
