Substance secreted in drawers to maintain cover-up? (7)
I believe the answer is:
elastic
'cover-up?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'substance secreted in drawers to maintain' is the wordplay.
I cannot quite see how this works, but
'substance' could be 'ti' (Ti is an example) and 'ti' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for elastic that I've seen before include "Material that stretches" , "Resilient" , "'Flexible, springy (7)'" , "Kind of band" , "Stretchable material" .)
