Opponent of Wade's last three letters from opponent of Borg (3)
I believe the answer is:
roe
'opponent of wade's' is the definition.
(as in Roe vs Wade, US court case)
'last three letters from opponent of borg' is the wordplay.
I cannot quite understand how this works, but
'from' could be 'o' (I've seen this in other clues) and 'o' is located in the answer.
The remaining letters 're' 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 roe that I've seen before include "shy animal" , "If hard, eggs" , "Lobster's ripe ovary" , "Food from fish" , "Mass of fish eggs" .)
