Can be claimed to have its point (7)
I believe the answer is:
decimal
'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' is an anagram indicator.
'claimed' is an anagram of 'DECIMAL'.
'to have its' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for decimal that I've seen before include "System based on ten" , "Based on the number 10" , "Claimed, wrongly, to have this currency" , "System based on 10" , "In base ten" .)
