You might say spectacles in which looker gets with listener (7)
I believe the answer is:
eyewear
'you might say spectacles in' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'looker gets with listener' is the wordplay.
'looker' becomes 'eye' (I've seen this in another clue).
'gets' means one lot of letters go next to another.
'with' becomes 'w' (abbreviation).
'listener' becomes 'ear' (body part which hears or listens).
'eye'+'w'+'ear'='EYEWEAR'
'which' acts as a link.
Can you help me to learn more?
(Other definitions for eyewear that I've seen before include "glasses" , "viewers' protection" , "Eg, spectacles, contact lenses" , "reading aids" .)
