Salines, central drips, lined after switches (6)
I believe the answer is:
retail
'salines central' is the definition.
Both the definition and answer are adjectives. Perhaps you can see an association between them that I can't see?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for retail that I've seen before include "Form of sales" , "This trade sells direct to the public" , "Not wholesale" , "Sell in small quantities" , "Relate details" .)
