An opening perhaps education provides (4)
I believe the answer is:
apse
'an opening' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'perhaps education provides' is the wordplay.
'provides' says the answer is hidden in the clue.
'APSE' can be found hidden inside 'perhaps education'.
Can you help me to learn more?
(Other definitions for apse that I've seen before include "Semicircular recess in church" , "Architectural feature in a church" , "Peas (anag) - found in church" , "Recess with domed rof in a church" , "inside church?" .)
