Stare fixedly at London landmark before dance (7)
I believe the answer is:
eyeball
'stare fixedly' is the definition.
'eyeball' can be an answer for 'stare' (I've seen this before). I'm not sure about the 'fixedly' bit.
'london landmark before dance' is the wordplay.
'london landmark' becomes 'eye' (the London Eye).
'before' means one lot of letters go next to another.
'dance' becomes 'ball' (ball is a kind of dance).
'eye'+'ball'='EYEBALL'
'at' acts as a link.
Can you help me to learn more?
(Other definitions for eyeball that I've seen before include "It was cut in Un Chien Andalou" , "Closely examine" , "Stare at closely; organ" , "One faces one in confrontation" , "Optical sphere within lids" .)
