Sanction production of a paper without vowels and egg-shaped (8)
I believe the answer is:
approval
'sanction' is the definition.
(I know that sanction can be written as approval)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for approval that I've seen before include "Favourable opinion or official permission" , "On it, goods may be returned if not satisfactory" , "Ratification" , "Esteem - permission" , "Confirmation" .)
