Overpriced in Paris, the towering spire? (7)
I believe the answer is:
steeple
'towering spire?' is the definition.
'steeple' can be an answer for 'spire?' (synonyms). I'm not sure about the 'towering' bit.
'overpriced in paris the' is the wordplay.
'overpriced' becomes 'steep' (I've seen this in another clue).
'in paris the' becomes 'le' ('the' in French).
'steep'+'le'='STEEPLE'
Can you help me to learn more?
(Other definitions for steeple that I've seen before include "Tall tower with spire on top of church" , "point" , "Pointed structure" , "Sort of chase" , "that the church may be under" .)
