See below platform (10)
I believe the answer is:
understand
'see' is the definition.
(I know that see can be written as understand)
'below platform' is the wordplay.
'below' becomes 'under' (synonyms).
'platform' becomes 'stand' (stand is a kind of platform).
'under'+'stand'='UNDERSTAND'
(Other definitions for understand that I've seen before include "Perceive the meaning of" , "Comprehend" , "Grasp - sympathise" , "See" , "Twig" .)
