It seems that "'S e deagh mhadainn a th' ann" is equivalent to "Tha deagh mhadainn ann".
The latter is used for "There is [something]" - e.g. Tha reòthadh ann - "There is frost". I guess it's correct to say this in either way.
I think you can say
" 'S e latha math a th' ann"?
So can you also say
" 'S e deagh mhadainn a th' ann?"?
And if not, why?
I guess this answers my question:
Madainn mhath Iain, 's e deagh mhadainn a th' ann.
Another correct solution:
Madainn mhath Iain, tha deagh mhadainn ann.
So both are right?
I am so relieved that I am not the only one whom is questioning this.
'S e madainn mhath a th' ann
Tha deagh mhadainn ann?
My head is spinning..
I have the same question as Stella. When can the various forms be used?
