Britannica editor Jeff Wallenfeldt provides an overview of the Irish language.
The Latin alphabet was introduced to Ireland by British missionaries in the 5th century CE. Following this introduction, it soon began to be used for writing the Irish language.1
While the earliest evidence of Irish writing consists of ogham inscriptions from the 4th and 5th centuries, the use of the Roman (Latin) alphabet for Irish literature is documented beginning in the 8th century, though some compositions from the 6th and 7th centuries have been preserved in later manuscripts.23
