Sorry, Simon, I’m afraid you’ve gone astray with the conjugated forms of trooid in Gaelg – you’ve copied and pasted them from Gaeilge or Gàidhlig. For the record, the forms are: –
1s. My hrooid
2s. Dty hrooid
3s. E hrooid (m.)
3s. E trooid (f)
Pl. Nyd drooid
Also, the IPA you show is for the word eddyr.
