See metal-clad wife's rampant companion (7)
I believe the answer is:
norwich
'see' is the definition.
(I've seen this before)
'metal-clad wife's rampant companion' is the wordplay.
'metal' becomes 'iron' (iron is a metal).
'clad' means one lot of letters goes inside another (clad can mean covered by).
'wife' becomes 'w' (abbreviation).
'rampant' is a reversal indicator (rampant can mean rearing).
'companion' becomes 'ch' (Companion of Honour).
'iron' going around 'w' is 'iwron'.
'iwron' back-to-front is 'norwi'.
'norwi'+'ch'='NORWICH'
(Other definitions for norwich that I've seen before include "English city" , "East Anglian city" , "See" , "Juliana of - (Revelations of Divine Love)" , "Norfolk city" .)
