Cutting rhubarb? (4)
I believe the answer is:
barb
'cutting' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'rhubarb?' is the wordplay.
'BARB' is hidden within the letters.
But, I am not sure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for barb that I've seen before include "part of a habit" , "criticism" , "Hurtful comment" , "Small prong on larger point" , "Pointed part - gibe" .)
