Hope for a steeple (6)
I believe the answer is:
aspire
'hope for' is the definition.
(thesaurus)
'a steeple' is the wordplay.
'steeple' becomes 'spire' (synonyms).
'a'+'spire'='ASPIRE'
(Other definitions for aspire that I've seen before include "Is a rep (anag.)" , "Aim, have an ambitious plan" , "Aim (for higher things)" , "Have ambition (to achieve something)" , "Desire (to reach higher things)" .)
