Figure cathedral is majestic (7)
I believe the answer is:
stately
'majestic' is the definition.
(thesaurus)
'figure cathedral' is the wordplay.
'figure' becomes 'stat' (I've seen this before).
'cathedral' becomes 'ely' (cathedral city in Cambridgeshire).
'stat'+'ely'='STATELY'
'is' acts as a link.
(Other definitions for stately that I've seen before include "` `In Xanadu did Kubla Khan / A ....... pleasure-dome decree' ' (Coleridge)" , "Dignified and impressive" , "Formal; type of home" , "Impressive in manner" , "Courtly; imposing" .)
