Standing one a beer outside "The Orb and Sceptre"? (7)
I believe the answer is:
regalia
'the orb and sceptre?' is the definition.
I can't judge whether this defines the answer.
'standing one a beer outside' is the wordplay.
'standing' is a reversal indicator.
'one' becomes 'I' (Roman numeral).
'beer' becomes 'lager' (lager is a kind of beer).
'outside' is an insertion indicator.
'a'+'lager'='alager'
'i' placed into 'alager' is 'ailager'.
'ailager' written backwards gives 'REGALIA'.
Can you help me to learn more?
(Other definitions for regalia that I've seen before include "Ceremonial robes" , "Trappings of royalty" , "Algeria (anag)" , "Royal insignia" , "Royal accoutrements" .)
