Code for identifying English conifer (4)
I believe the answer is:
pine
'conifer' is the definition.
(I know that pine is a type of conifer)
'code for identifying english' is the wordplay.
'code' becomes 'pin' (a PIN number is a 4-digit code).
'for' is a charade indicator (letters next to each other).
'identifying english' becomes 'e' (abbreviation. I am not sure about the 'identifying' bit.).
'pin'+'e'='PINE'
Can you help me to learn more?
(Other definitions for pine that I've seen before include "A tree to grieve for" , "Long - timber" , "type of wood" , "Evergreen conifer" , "Thirst" .)
