Workshops working to supply e-tailers (8)
I believe the answer is:
ateliers
'workshops' is the definition.
(I've seen this before)
'supply e-tailers' is the wordplay.
'supply' is an anagram indicator (in a supple way).
'e'+'tailers'='etailers'
'etailers' with letters rearranged gives 'ATELIERS'.
'working to' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for ateliers that I've seen before include "Accommodation" , "Artist's workrooms" , "Artists' studios" , "workshops" .)
