Donate total one's given, say (7,7)
I believe the answer is:
present perfect
'donate total one's' is the definition.
I can't judge whether this definition defines the answer.
'say' is the wordplay.
I cannot really understand how this works, but
'say' could be 'present' (presenting is a kind of saying) and 'present' is found in the answer.
The remaining letters 'perfect' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'given' acts as a link.
Can you help me to learn more?
(Other definitions for present perfect that I've seen before include "Tense" , "writing the briefest of thank you letters?" , "giver is happy to hear this?" , "I have left in this?" .)
