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 a link between them that I don't see?
'take a seat' is the wordplay.
'seat' can be anagrammed to 'TEAS'.
However, I'm not clear how the anagram 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" .)
