Wish for a steeple (6)
I believe the answer is:
aspire
'wish' is the definition.
(I've seen this before)
'a steeple' is the wordplay.
'steeple' becomes 'spire' (synonyms).
'a'+'spire'='ASPIRE'
'for' is the link.
(Other definitions for aspire that I've seen before include "Desire (to reach higher things)" , "Earnestly desire (to achieve something)" , "Aim at, work towards" , "Have hopes (to achieve something)" , "Wish to rise (to)" .)
