Around mid-March, a beast is bad tempered (6)
I believe the answer is:
morose
'bad tempered' is the definition.
Both the answer and definition are adjectives.
Maybe you can see a link between them that I can't see?
'around mid-march a beast' is the wordplay.
'around' indicates putting letters inside.
'mid' says to take the centre.
'a beast' becomes 'moose'.
The middle of 'march' is 'r'.
'r' put into 'moose' is 'MOROSE'.
'is' is the link.
Can you help me to learn more?
(Other definitions for morose that I've seen before include "blue" , "Sullen or glum." , "Sullen and ill-tempered" , "Peevish and gloomy" , "in a grumpy mood" .)
