To exalt one so idle is wrong (7)
I believe the answer is:
idolise
'to exalt' is the definition.
('exalt'->'idolize' is in my internal thesaurus and 'ize'->'ise')
'one so idle is wrong' is the wordplay.
'one' becomes 'i' (Roman numeral).
'is wrong' indicates an anagram.
'so'+'idle'='soidle'
'soidle' with letters rearranged gives 'dolise'.
'i'+'dolise'='IDOLISE'
(Other definitions for idolise that I've seen before include "Pay excessive attention to" , "Revere, love greatly" , "Pay inordinate attention to" , "Revere (someone) greatly or excessively" , "Doilies to worship" .)
