Locations of spectacles, say (5)
I believe the answer is:
sites
'locations' is the definition.
(site is a kind of location)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for sites that I've seen before include "Is set (anag)" , "Is set among building locations" , "places" , "Locations or positions, as for building" , "internet locations" .)
