Dries veg out and separates (8)
I believe the answer is:
diverges
'separates' is the definition.
The answer and definition can be both to do with motion as well as being verbs in their -s form.
Maybe they are linked in a way I don't understand?
'dries veg out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'dries'+'veg'='driesveg'
'driesveg' with letters rearranged gives 'DIVERGES'.
'and' is the link.
Can you help me to learn more?
(Other definitions for diverges that I've seen before include "Separates or gets further apart" , "Separates and goes in different directions" .)
