An excellent view of the tower we hear (6)
I believe the answer is:
eyeful
'an excellent view' is the definition.
'eyeful' can be an answer for 'view' (eyeful is a kind of view). I'm not certain of the 'an excellent' bit.
'the tower we hear' is the wordplay.
'the tower' becomes 'eiffel' (Eiffel Tower is an example).
'we hear' shows a homophone (sound like).
'eiffel' is a homophone of 'EYEFUL'.
'of' is the link.
Can you help me to learn more?
(Other definitions for eyeful that I've seen before include "Does a pupil contribute to this" , "Here butcher's" , "fascinating spectacle?" , "Attractive sight" , "Something worth looking at" .)
