Noun
Irish Gaelic
A boreen is a small country lane, the kind that has grass growing up the middle of its single lane. Little more than a cartpath.

Boreens are often lined by close stone walls, so on the rare occasion one meets traffic comeing the other way, it can be all but impossible to pass without one motorist backing up for quite a distance.
We were out driving on the boreens of Roscommon when we came upon what I believe is the finest pub in the Republic.
