Irish language indigenous to County Donegal
Ulster
Ulster Irish is the dialect spoken in the Gaeltacht regions of Donegal. These regions contain all of Ulster's communities where Irish has been spoken in an unbroken line back to when the language was the dominant language of Ireland. The Irish-speaking communities in other parts of Ulster are a result of language revival – English-speaking families deciding to learn Irish. Census data shows that 4,130 people speak it at home.
Linguistically, the most important of the Ulster dialects today is that which is spoken, with slight differences, in both Gweedore (Gaoth Dobhair = Inlet of Streaming Water) and The Rosses (na Rossa).
Ulster Irish sounds quite different from the other two main dialects. It shares several features with southern dialects of Scottish Gaelic and Manx, as well as having many characteristic words and shades of meanings. However, since the demise of those Irish dialects spoken natively in what is today Northern Ireland, it is probably an exaggeration to see present-day Ulster Irish as an intermediary form between Scottish Gaelic and the southern and western dialects of Irish. Northern Scottish Gaelic has many non-Ulster features in common with Munster Irish.
One noticeable trait of Ulster Irish, Scots Gaelic and Manx is the use of the negative particle cha(n) in place of the Munster and Connacht ní. Though southern Donegal Irish tends to use ní more than cha(n), cha(n) has almost ousted ní in northernmost dialects (e.g. Rosguill and Tory Island), though even in these areas níl "is not" is more common than chan fhuil or cha bhfuil. Another noticeable trait is the pronunciation of the first person singular verb ending -(a)im as -(e)am, also common to Man and Scotland (Munster/Connacht siúlaim "I walk", Ulster siúlam).
