Flags, having no strong points (7)

'flags' is the definition.
The answer and definition can be both related to change as well as being verbs in their -s form.
Maybe you can see an association between them that I don't see?

'no strong points' is the wordplay.
I cannot quite understand how this works, but
'no' could be 'n' (common abbreviation y/n) and 'n' is present in the answer.
'points' could be 'we' and 'we' is present in the answer.
The remaining letters 'akes' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

'having' acts as a link.
