Could put years on a girl, no doubt (1,4,3)
I believe the answer is:
i dare say
'girl no doubt' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'could put years on a' is the wordplay.
I cannot really understand how this works, but
an anagram of 'years' is 'resay' which is present in the answer.
'a' is found in the answer.
The remaining letters 'id' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for i dare say that I've seen before include "Probably" , "It wouldn't surprise me" , "It is probable" , "Quite possibly" , "Maybe" .)
