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 quite see how this works, but
'about' could be 'c' (abbreviation for circa) and 'c' is found in the answer.
'love' could be 'o' (love means zero in tennis) and 'o' is located in the answer.
The remaining letters 'vie' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'there's' is the 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" .)
