Lawyer confused about old special plural (5,2)
I believe the answer is:
royal we
'plural' is the definition.
(I know that royal we is a type of nosism)
'lawyer confused about old' is the wordplay.
'confused' is an anagram indicator.
'about' indicates putting letters inside.
'old' becomes 'o' (abbreviation as in OT - Old Testament).
'lawyer' with letters rearranged gives 'ryalwe'.
'ryalwe' going around 'o' is 'ROYAL WE'.
'special' is the link.
This may not be right. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for royal we that I've seen before include "Coming from eg Edward, Henry or Charles" , "Monarch's way of referring to themselves" , "for King George I?" , "Monarch's use of the first person plural" , "Queen's pronoun" .)
