Exorbitant French article from tower (7)
I believe the answer is:
steeple
'tower' is the definition.
(I know that steeple is a type of tower)
'exorbitant french article' is the wordplay.
'exorbitant' becomes 'steep' (synonyms).
'french article' becomes 'le' (definite article in French).
'steep'+'le'='STEEPLE'
'from' acts as a link.
(Other definitions for steeple that I've seen before include "Tall building" , "Pointed church tower" , "Pointed structure" , "Jack up this?" , "Pet eels (anag)" .)
