'keep away from' is the definition.
(I've seen this before)

'a'+'void'='AVOID'

'to' acts as a link.

Can you help me to learn more?

(Other definitions for avoid that I've seen before include "Shy away from" , "Keep away from (someone/something)" , "Desist" , "Steer clear of, dodge" , "Duck" .)

I've seen this clue in The Globe and Mail.
