Conservatives exposed Liberal - you can see through it (5)
I believe the answer is:
oriel
'can see through it' is the definition.
I can't judge whether this defines the answer.
'conservatives exposed liberal' is the wordplay.
'conservatives' becomes 'Tories' (informal term for the Conservative Party).
'exposed' means to look at the middle letters (outside letters removed).
'liberal' becomes 'l' (abbreviation).
The central letters of 'tories' are 'orie'.
'orie'+'l'='ORIEL'
'you' acts as a link.
Can you help me to learn more?
(Other definitions for oriel that I've seen before include "Overhanging recess (window)" , "Recessed bay window" , "Upper room window" , "This window projects from upper storey" , "polygonal recess" .)
