Why does the exercise use "heddychwraig"? Does it change the meaning of the word slightly?
Looking up 'pacifist' at https://geiriaduracademi.org/ I got:
heddychwr (m); heddychwraig (f)
So I assume that heddychwr would be a male pacifist and that heddychwraig would be a female pacifist.
Would 'Wyt ti heddychwr?' work or would it need to be 'Heddychwr wyt ti?'
It is usual to use the emphatic pattern with this kind of question asking about an occupation, name, role, and so on. The item being emphasised is put at the front of the sentence, here Heddychwr ...?
Thanks as usual for your prompt reply ibisc.
