Batter in upturned polystyrene pots (6)
I believe the answer is:
opener
'batter' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'in upturned polystyrene pots' is the wordplay.
'upturned' is a reversal indicator.
'in' says the answer is hidden in the clue.
'renepo' can be found hidden inside 'polystyrene pots'.
'renepo' written backwards gives 'OPENER'.
Can you help me to learn more?
(Other definitions for opener that I've seen before include "batsman facing new ball" , "introduction" , "A key or a bottle top remover" , "Kitchen item" , "First part" .)
