What's the non-mutated form of 'wife'?
'Gwraig' is the non-mutated form of wife, thanks for commenting on this as I've realised that the non-mutated form comes after the mutated form in the course, something to rectify for the revised course.
If you look up mutated words on www.gweiadur.com or on Ap Geiriaduron they will show you the unmutated word and its meanings.
sounds almost like ddraig! how nice)
