Auraicept na n-Éces ([arakʲept na neːgʲes], "the scholars' [éices] primer [airaiccecht]"; in the modern Gaelic languages: Irish: Aiceacht na nÉigeas, Scottish Gaelic: Uraiceachd nan Éigeas) was historically thought to be a 7th-century work of Irish grammarians, written by a scholar named Longarad. The core of the text may date to the mid-7th century, but much material was added between that date and the production of the earliest surviving copy in the 12th century.
