Editor's rule-breaking escalates quickly in Chambers (8)
I believe the answer is:
bedrooms
'chambers' is the definition.
('bedroom' can be a synonym of 'chamber')
'editor's rule-breaking escalates quickly' is the wordplay.
'editor' becomes 'ed' (abbreviation).
'rule' becomes 'r' (abbreviation for rule).
'breaking' means one lot of letters goes inside another.
'escalates quickly' becomes 'booms' (I can't justify this - if you can you should give a lot more credence to this answer).
'ed'+'r'='edr'
'edr' put within 'booms' is 'BEDROOMS'.
'in' is the link.
Can you help me to learn more?
(Other definitions for bedrooms that I've seen before include "Sleeping quarters" , "Sleeping chambers" , "Sleeping areas" , "Sleeping spaces" , "Dom robes up after nights spent in them" .)
