Can be claimed to make a point (7)
I believe the answer is:
decimal
'a point' is the definition.
(I have seen 'The point' mean 'decimal' so perhaps 'point' could also mean 'decimal')
'can be claimed' is the wordplay.
'can be' indicates anagramming the letters.
'claimed' anagrammed gives 'DECIMAL'.
'to make' is the link.
(Other definitions for decimal that I've seen before include "System based on 10" , "fraction" , "Using powers of ten" , "Based on the number 10" , "Sort of coinage" .)
