Take a seat for light refreshments (4)
I believe the answer is:
teas
'light refreshments' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being plural nouns.
Perhaps you can see an association between them that I don't see?
'take a seat' is the wordplay.
'seat' can be anagrammed to 'TEAS'.
However, I am unsure how this is indicated.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for teas that I've seen before include "Hot drinks" , "Beverage made by steeping leaves in water" , "Afternoon meals" , "Beverages from leaves" .)
