"Nyrs iechyd"

Translation: Health nurse

[Catherine-Brown]

Why can't it be healthy nurse? Is that Nyrs inch?

It would be "nyrs iach" or "nyrs iachus". I'm not sure whether there is any difference between "iach" and "iachus" but Ap Geiriaduron says both mean "healthy".

Judging by the GPC entries (iach, iachus), iach is "healthy" like a person (i.e. the person has health), iachus is "healthy" like food (i.e. the food promotes health).
