Retail worker overwhelmed by thank-you letters' positive conclusions (11)
I believe the answer is:
merchandise
'retail' is the definition.
(thesaurus)
'worker overwhelmed by thank-you letters' positive conclusions' is the wordplay.
I cannot really understand how this works, but
'worker' could be 'hand' (hand is a kind of worker) and 'hand' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for merchandise that I've seen before include "Goods for trading" , "Wares" , "traffic" , "Goods for sale" , "Items for sale" .)
