There is indeed an Irish word for parents. 'Tuismitheoiri' is the Irish for 'Parents' (this is commonly abbreviated to 'tuisti' in the spoken language.)
'Athair agus Mathair' is the Irish for 'Father and Mother'
I am a young, Irish, primary school teacher with a deep knowledge of the Irish language. I would love to share our beautiful language with the Irish, Irish-Americans or Americans (or indeed people of any nationality) in the USA this summer 2001 during our school holidays in July and August with a colleague (Anne). If you know of anyone who would be interested in employing us for all, or part of this time, I would be very grateful to you if you would forward their details to me, or mine to him/her, so that we may discuss it further.
Thanking you for any information,
Is mise le meas,
