Adele occasionally accommodated by fruit seller (6)
I believe the answer is:
pedlar
'seller' is the definition.
(I know that pedlar is a type of seller)
'adele occasionally accommodated by fruit' is the wordplay.
'occasionally' indicates alternate letters.
'accommodated by' is an insertion indicator.
'fruit' becomes 'pear' (pear is a kind of fruit).
The alternating letters of 'adele' are 'dl'.
'dl' going within 'pear' is 'PEDLAR'.
(Other definitions for pedlar that I've seen before include "Travelling merchant" , "Itinerant trader" , "Itinerant seller" , "Person who sells door-to-door" , "Travelling vendor of small goods" .)
