A singular spectacle? (8)
I believe the answer is:
eyeglass
'spectacle?' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'a singular' is the wordplay.
I cannot quite understand how this works, but
'a' is present in the answer.
'singular' could be 's' (abbreviation in grammar) and 's' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for eyeglass that I've seen before include "Lens for aiding defective vision" , "Monocle, or spectacles in plural" , "Aid to vision" .)
