I think I'm quite happy with all my words, but struggled when it came to putting them in pairs. 'Groove' seems to work on its own, but I can't really pair it up.
Stuck on last bit too (have 2 pairs & 2 odd).
Could the one in the 4th row be GINGER? Can't be Nigger!!!
And in row 3: I haqve R?EV?G and can make nothing of it, either for horse or car variants (anagrams of course).
ANY hint greatly appreciated!
