Plant conceals dog sold in shop (8)
I believe the answer is:
retailed
'sold in shop' is the definition.
'retailed' can be an answer for 'sold' (retailing is a kind of selling). I'm not certain of the 'in shop' bit.
'plant conceals dog' is the wordplay.
I cannot quite see how this works, but
'dog' could be 'tail' (synonyms) and 'tail' is located in the answer.
'plant' could be 'reed' (reed is a kind of plant) and 'reed' is located in the leftover letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for retailed that I've seen is " Sold".)
