According to Ó Dónaill's dictionary "Foclóir Gaelige-Bearla", "banchríoch" means, "Green boundary strip between fields".

According to Terence Patrick Dolan's "A Dictionary of Hiberno-English", "banóg, also bawnogue", means "a patch of green". He gives the useage example, "they were dancing on the bawnogue until the crack of dawn".

However, as well as being a general noun, it's also a specific place name. Two examples are 1. The Bawnogue, just over the Wexford border into Co. Kilkenny, a few miles east of the town of Borris. It was her that Father John Murphy ("of Boolavogue") spent 26-28 June 1798 on the run before being captured and executed a few days later.
2. Bawnogue is also the name given to an area of Clondalkin, in south west Dublin City.
