suantraí as sung by Anúna:
Mo ghaol, mo ghrá 'gus m'eadúil thú
Mo stoirín úr is m'fhéirín thú
Mo mhacán álainn scéimheach thú
Chan fiú mé féin bheith 'd dháil
Alleluia

O you my kin, my love and my idol
My darling and my precious thing
My beautiful little son
With just myself to care for you
Alleluia
