Work towards a steeple (6)
I believe the answer is:
aspire
'work towards' is the definition.
I can't judge whether this defines the answer.
'a steeple' is the wordplay.
'steeple' becomes 'spire' (synonyms).
'a'+'spire'='ASPIRE'
Can you help me to learn more?
(Other definitions for aspire that I've seen before include "Have hopes (to achieve something)" , "Hope (to do something)" , "Seek (to do something)" , "Earnestly desire (to achieve something)" , "Have an ambitious plan or a lofty goal" .)
