Patronising husband staggered I ran Hotel Grand (6-4-4)
I believe the answer is:
holier-than-thou
'patronising' is the definition.
'husband staggered i ran hotel grand' is the wordplay.
'husband' becomes 'h'.
'staggered' indicates anagramming the letters.
'grand' becomes 'thou' (synonyms).
'i'+'ran'+'hotel'='iranhotel'
'iranhotel' anagrammed gives 'olierthan'.
'h'+'olierthan'+'thou'='HOLIER-THAN-THOU'
(Other definitions for holier-than-thou that I've seen before include "Sanctimonious" , "Self-righteous" .)
