What’s in decanter I ordered earlier? (8)
I believe the answer is:
anterior
'earlier?' is the definition.
(I've seen this in another clue)
'what's in decanter i ordered' is the wordplay.
'what's in' says the answer is hidden in the clue.
'ANTERIOR' is hidden within 'decanter i ordered'.
(Other definitions for anterior that I've seen before include "Previous, to the fore" , "Nearer the front; prior (to)" , "Located before, in time or place" , "Towards the front" , "Nearer the front; earlier" .)
