Rather high, the Parisian church tower (7)
I believe the answer is:
steeple
'church tower' is the definition.
(I've seen this before)
'rather high the parisian' is the wordplay.
'rather high' becomes 'steep' (similar in meaning. I am not sure about the 'rather' bit.).
'the parisian' becomes 'le' (definite article in French).
'steep'+'le'='STEEPLE'
Can you help me to learn more?
(Other definitions for steeple that I've seen before include "Pointed structure" , "point" , "Tall tower with spire on top of church" , "Pet eels (anag)" , "Sort of chase" .)
