tat- are confined almost exclusively to the diocese of Clogher, which covers Counties Fermanagh and Monaghan, and the barony of Clogher in County Tyrone), and cannot be confused with any other Irish word. The use of the term can also be seen in the diocese of Clogher parish of Inniskeen area within Louth where the townlands of Edenagrena, Drumsinnot, Killaconner and Torpass were referred to collectively as “the four tates of Ballyfoylan.” In modern townland names the prefix pol- is widely found throughout western Ireland, its accepted meaning being "hole" or "hollow". In County Cavan, which contains over half of all townlands in Ulster with the prefix pol-, some should probably be better translated as "the poll of ...". In County Tyrone the following hierarchy of land divisions was used: "ballybetagh" (, meaning "cattle place"), "ballyboe", "sessiagh" (, meaning sixth part of a quarter), "gort" and "quarter" (). In County Fermanagh the divisions were "ballybetagh", "quarter" and "tate". Further subdivisions in Fermanagh appear to be related to liquid or grain measures such as "gallons", "pottles" and "pints". In Ulster the ballybetagh was the territorial unit controlled by an Irish sept, typically containing around 16 townlands. Fragmentation of ballybetaghs resulted in units consisting of four, eight and twelve townlands. One of these fragmented units, the "quarter", representing a quarter of a ballybetagh, was the universal land denomination recorded in the survey of County Donegal conducted in 1608. In the early 17th century 20 per cent of the total area of western Ulster was under the control of the church. These "termonn" lands consisted likewise of ballybetaghs and ballyboes, but were held by erenaghs instead of sept leaders. Other units of land division used throughout Ireland include: In County Tipperary, "capell lands" and "quatermeers". A "capell land" consisted of around 20 great acres (one great acre equalled 20 English acres). In the province of Connacht, "quarters" and "cartrons" (, also anglicised as "carrowmeer"), a quarter being reckoned as four cartrons, and each cartron being 30 acres. The quarter has also been anglicised as "carrow", "carhoo" or "caracute" (). In County Clare, as in Connacht, "quarters", "half-quarters" (), "cartrons" and "sessiagh". Here a "half-quarter" equated to around 60 acres, a "cartron" equated to around 30 acres and a "sessiagh" was around 20 acres. "Cartrons" were also sometimes called "ploughlands" or "seisreagh" (, meaning a team of horses yoked to a plough). Thomas Larcom,
