Cancel article withdrawn from yearbook (5)
I believe the answer is:
annul
'cancel' is the definition.
(I know that annul is a more specific form of cancel)
'article withdrawn from yearbook' is the wordplay.
I cannot really see how this works, but
'article' could be 'an' (indefinite article) and 'an' is found 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 annul that I've seen before include "Obligation" , "Countermand" , "Cancel, make void" , "Quash" , "Scrap" .)
