Check cots niece sent over, having purchased what was available from retailer (2,5)
I believe the answer is:
in stock
'purchased what was available from retailer' is the definition.
I can't tell whether this definition defines the answer.
'check cots niece sent over having' is the wordplay.
'having' says the answer is hidden in the clue.
'sent over' says the letters should be written backwards.
'kcotsni' can be found hidden inside 'check cots niece'.
'kcotsni' backwards is 'IN STOCK'.
Can you help me to learn more?
(Other definitions for in stock that I've seen before include "On the shelf" , "Where one may have cooked any meat" , "Held by a shop" , "available" .)
