Prepare pupils for exam? (6)
I believe the answer is:
dilate
'prepare' is the definition.
The answer and definition can be both related to change as well as being verbs in their base form.
Perhaps you can see a link between them that I can't see?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for dilate that I've seen before include "Enlarge or widen, like pupils perhaps" , "Widen as eyes may" , "Make wider or larger" , "Widen like eye pupils" , "Speak or write at length - widen" .)
