When it comes to counting objects, my understanding is that you have to use the word ceann amháin/__ cinn/___ gcinn depending on the total.

Do you always have to use ceann or one of the other forms, or can you repeat the object being counted instead?

For example, could I use trí sheomra when referring to the number of rooms in my house? Or must I use trí cinn?


Secondly, are Shéamas and Shéamuis pronounced differently? As in 'do Shéamas' or 'do Shéamuis'? (do hey-mish? or possibly hey-mwish?)

Cheannaigh mé barraí seacláide, agus tá trí cinn agam anois.

Is this what you are going for? That is, referring back to the items bought after having first mentioned them?


Séamus is the basic form, and when you call to someone by the same name you can change it to A Shéamuis and when you say thug mé ceann amháin do Shéamus, you change the beginning but not the end

Yeah, they are both different, 'saymus', 'haymus', 'ah haymwish'

I was thinking more in terms of responding to questions about the house.

So... Cé mhéad seomra atá sa teach?

I understand that it's incorrect to just say 'Trí' in response. But can you say Trí sheomra or does it have to be trí cinn?

I understand using lenition when addressing someone (depending on the first letter in their name). But for 'do'...you're saying it's always 'do Shéamus' rather than 'do Shéamuis? Actually the example used in Ó Dónaill's exercise book is do Shéamas.

Séamas
A Shéamais (or would it change to A Shéamuis?)
do Shéamas

You can say trí sheomra (three rooms) or trí cinn (three of them, literally: three heads).

Séamas and Séamus are just different spellings (like John and Jon in English). They are pronounced the same.

Séamas
A Shéamais
Do Shéamas

Séamus
A Shéamuis
Do Shéamus

Tuigim anois. Go raibh maith agaibh. Thanks to you both.

I thought that they were essentially the same name, but wasn't sure. Like Siobhán and Siúbhan in Ulster?
