Special gear and excellent beer from the rear (7)
I believe the answer is:
regalia
'special gear' is the definition.
'regalia' can be an answer for 'gear' (regalia is a kind of gear). I'm unsure of the 'special' bit.
'excellent beer from the rear' is the wordplay.
'excellent' becomes 'ai' (resembles 'A1', old-fashioned term for excellent).
'beer' becomes 'lager' (type of beer).
'from the rear' says the letters should be written in reverse.
'ai'+'lager'='ailager'
'ailager' written backwards gives 'REGALIA'.
'and' is the link.
Can you help me to learn more?
(Other definitions for regalia that I've seen before include "Finery" , "Paraphernalia indicative of high office" , "Royal items" , "Orb and sceptre, for example" , "Algeria (anag)" .)
