A refreshing extract of senna pods (3)
I believe the answer is:
nap
'a refreshing extract' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'of senna pods' is the wordplay.
'of' says the answer is hidden in the clue.
'NAP' is hidden in the letters of 'senna pods'.
Can you help me to learn more?
(Other definitions for nap that I've seen before include "one akin to whist" , "Raised fibres on surface of cloth or leather" , "Siesta" , "Quick sleep; raised pile" , "A brief sleep, forty winks" .)
