Wherein a clerk can get a bad chill (6)
I believe the answer is:
office
'wherein a clerk' is the definition.
I can't tell whether this defines the answer.
'get a bad chill' is the wordplay.
'get' means one lot of letters go next to another.
'a bad' becomes 'off' (I've seen this before).
'chill' becomes 'ice' (icing is a kind of chilling).
'off' put next to 'ice' is 'OFFICE'.
'can' is the link.
Can you help me to learn more?
(Other definitions for office that I've seen before include "Administration room" , "Room for working" , "Workroom" , "Post - bureau" , "Post - place of work" .)
