"Boreen" also appears sometimes in names of minor urban roads such as Saint Mobhi Bóithrín (Irish: Bóithrín Mobhí), commonly known as Mobhi Boreen in Glasnevin, Dublin. To be considered a boreen the road or path should not be wide enough for two cars to pass and have grass growing in the middle.
The word "boreen" comes from the Irish word bóithrín, which in turn comes from bóthar. In origin, a bóthar was a cow path, a track the width of two cows, so bóithrín meant a little cow path. Bóthar was one of the five types of road identified in medieval Irish legal texts, the others being slige (on which two chariots could pass), rót (on which one chariot and two riders could pass), lámraite (a road connecting two major roads) and tógraite (a road leading to a forest or a river).
