Referring to follower of this sort of trade (6)
I believe the answer is:
retail
'trade' is the definition.
(thesaurus)
'referring to follower' is the wordplay.
'referring to' becomes 're' ('re' means regarding or about).
'follower' becomes 'tail' (tail is a kind of follower).
're'+'tail'='RETAIL'
'of this sort of' acts as a link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for retail that I've seen before include "sort of sale" , "I alter for trade that sells to public" , "This trade sells to the general public" , "Sale of goods to customers" , "Narrate or sell to public" .)
