Man breaking law at her second majestic address (5,2)
I believe the answer is:
royal we
'majestic address' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'man breaking law at her second' is the wordplay.
'man' becomes 'roy' (I've seen this before).
'breaking' indicates anagramming the letters.
'at' means one lot of letters go next to another.
'her second' becomes 'e' (ond letter of 'her').
'law' anagrammed gives 'alw'.
'roy'+'alw'+'e'='ROYAL WE'
Can you help me to learn more?
(Other definitions for royal we that I've seen before include "Queen's pronoun" , "Monarch's use of the first person plural" , "Monarch's way of referring to themselves" , "Coming from eg Edward, Henry or Charles" , "for King George I?" .)
