Crossword Genius

Point or points to support (7)

Ross

I believe the answer is:

endorse

Here is my best explanation:

'support' is the definition.
(endorsing is a kind of supporting)

'point or points' is the wordplay.
'point' becomes 'end' (end is a kind of point**).
'points' becomes 'se'.
'end'+'or'+'se'='ENDORSE'

'to' is the link.
