Dip in retail, with area sapped of energy (5)
I believe the answer is:
salsa
'dip' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for salsa that I've seen before include "Chilli sauce" , "Hot dance - hot sauce" , "Saucy dance" , "fling?" , "Cuban dance music or spicy sauce" .)
