Treatment of 'is' in present tense.

• (en) The boy is in the garden. → mae y bachgen yn yr ardd. (note: yr → 'r is an open bug)
• (cy) mae'r bachgen yn yr ardd. → the boy is in the garden.

Yep, I know the pattern, the problem is that the post-generator insists on having a ~ before anything that it deals with -- This would mean that we have to have '~' before every vowel, which would be quite difficult. There is another possibility though, if we can't fix that and it would be to just use a plain transliterator to replace:

"aeiouwy + space + ~yr + space" with "aeiouwy'r + space"

Can you think of anything this might catch by accident? or is it a fairly safe search/replace? - Francis Tyers

I would go with this in the meantime - I think it's pretty safe. Note that your rule can act on both 'y' and 'yr'. The system is:

consonant + space + y + space + consonant

consonant + space + yr + space + vowel

vowel + 'r + space + consonant-or-vowel

Yes, the synthetic endings would be nice to sort out, but I don't think there would be a mutation here, so that's not a bug. - Donnek

The synthetic endings there are valid then? - Francis Tyers

Yes, in this case you would tend to say "y tŷ neisiaf". - Donnek

Hmm. Something odd about these. "y gath fudr" - fem adj has SM. Because the adj is short, you would also tend to use "butrach" and "butraf" in the second two. "peryglus" (dangerous) might be a better adj to use.- Donnek

There are a few adjectives which need to be marked as synthetic in the monodix. Is there likely to be an easy way of doing this? - Francis Tyers

As a rough rule for the time being, I would say you could mark any adj of 2 syllables or less as synthetic, but of course that is not scientific. - Donnek
