"This is Morag, she is happy."
Translation:Seo Mòrag, tha i toilichte.
Oh yes, sure is! (And I should know.)
There's a clue. The -ag suffix in Gaelic is grammatically feminine and a lot of feminine nouns end in -ag. Like tunnag and uinneag and feorag and ialtag.
Mòrag is the feminine diminutive of mòr, which is big or great, and is often held (at least in the baby-name books) to mean "Princess".
