A little sad in Northern Ireland wearing stiff plaster (8)
I believe the answer is:
downcast
'stiff plaster' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'a little sad in northern ireland wearing' is the wordplay.
I cannot really understand how this works, but
'a' is found in the answer.
'sad' could be 'down' (down can mean sad or unhappy) and 'down' is located in the answer.
The remaining letters 'cst' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for downcast that I've seen before include "Dejected and discouraged" , "Feeling despondent" , "Crestfallen" , "disheartened" , "Low in spirits" .)
