Getting angry about nothing is a funny thing (4)
I believe the answer is:
hoot
'a funny thing' is the definition.
The definition and answer can be both human attributes as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'getting angry about nothing' is the wordplay.
I cannot really understand how this works, but
'nothing' could be 'o' (O resembles 0) and 'o' is present in the answer.
'angry' could be 'hot' (I've seen this in another clue) and 'hot' is found within the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'is' is the link.
Can you help me to learn more?
(Other definitions for hoot that I've seen before include "Owlish cry" , "Owl's cry" , "Cry of owl" , "Screech" , "scream" .)
