Pole’s a cold place to be drinking when scoffing! (9)
I believe the answer is:
sarcastic
'pole's a cold place to be drinking when scoffing' is the definition.
I can't tell whether this defines the answer.
'pole's a cold place to be drinking when' is the wordplay.
'pole' becomes 's' (abbreviation for South, as in South Pole).
'a cold place' becomes 'arctic' (I can't explain this - if you can you should give a lot more credence to this answer).
'to be drinking' is an insertion indicator (inserted letters are consumed or drunk).
'when' becomes 'as' (eg 'when I walked' means 'as I walked').
'arctic' enclosing 'as' is 'arcastic'.
's'+'arcastic'='SARCASTIC'
Can you help me to learn more?
(Other definitions for sarcastic that I've seen before include "Using mocking irony" , "Mockingly humorous" , "Cruelly ironical" , "Using scornful language" , "Using mocking wit" .)
