Boreen

Boreen or bohereen (Irish: bóithrín, meaning "a little road", pronounced [bɔːˈriːn]) is a country lane, or narrow, frequently unpaved, rural road in Ireland. "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 in the case of a paved boreen it is desirable to have grass growing in the middle.

In parts of Ulster, a boreen is often called a loanin, an Ulster Scots word.
