There are 3 main dialects of Gaedilge. They are heard in the News broadcasts of Radio na Gaeltachta. They differ a little and systematically in pronunciation. Native speakers of one easily understand the others and Scots gaelic. The northern dialect was spoken north of a line roughly joining Dundalk and Bundoran. Its sounds reflect the nearness of Scotland. It is the second-largest in everyday use.
The main population spoke a central dialect a line joining Wexford to Ennis. It remains the largest in everyday use and literature.
A southern dialect was spoken in the south.
Mixtures occurred at the borders. A phonetic type spelling is taught since 1976 and learners vary in sounds.
