Tower in France sounds quite a sight (6)
I believe the answer is:
eiffel
'tower' is the definition.
(Eiffel Tower is an example)
'france sounds quite a sight' is the wordplay.
I cannot really see how this works, but
'france' could be 'ff' (an abbreviation for France written twice) and 'ff' is present in the answer.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for eiffel that I've seen before include "French structural engineer" , "& 20 Across Paris landmark" , "Famous tower designer" , "Great tower of Paris" , "Famous tourist tower in Paris" .)
