Yearn for a steeple (6)
I believe the answer is:
aspire
'yearn' is the definition.
(I've seen this in another clue)
'a steeple' is the wordplay.
'steeple' becomes 'spire' (synonyms).
'a'+'spire'='ASPIRE'
'for' acts as a link.
(Other definitions for aspire that I've seen before include "Have ambition or desire for praise" , "Aim, shoot for" , "Have ambitious plans for" , "Persia (anag.)" , "Seek (to do something)" .)
