Suggestion King should abandon foreign visit? (3)
I believe the answer is:
tip
'suggestion' is the definition.
(tip is a kind of suggestion)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for tip that I've seen before include "Give the likely winner for gratuity" , "expected by those who wait" , "tiny reward" , "Dump; hint" , "End; overbalance" .)
