Declare there's something gripping about love (5)
I believe the answer is:
voice
'declare' is the definition.
(I've seen this in another clue)
'something gripping about love' is the wordplay.
I cannot really see how this works, but
'about' could be 'c' (circa) and 'c' is located in the answer.
'love' could be 'o' (love means zero in tennis) and 'o' is present in the answer.
The remaining letters 'vie' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'there's' acts as a link.
Can you help me to learn more?
(Other definitions for voice that I've seen before include "Stated opinion" , "Power of speaking" , "Wallop" , "Speak of - mouthpiece" , "right to have a say" .)
