Hauled to the altar? (5)
I believe the answer is:
towed
'hauled' is the definition.
(I've seen this before)
'the altar?' is the wordplay.
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'altar?' becomes 'owed' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
't'+'owed'='TOWED'
'to' is the link.
Can you help me to learn more?
(Other definitions for towed that I've seen before include "Hauled" , "Dragged behind" , "drawn" , "Helped when powerless" , "Pulled along" .)
