debatable

Etymology

It is borrowed from Old French debatable (now French débattable),^[2][3] from debatre (“to debate”),^[2][3][4] originally "to fight", formed from de- (“down, completely”) and batre (“to beat”), from Latin battuō (“to beat”).^[3] The Shorter Oxford also allows an Anglo-Latin source, Medieval Latin debatabilis,^[4][2] and Merriam-Webster takes that Medieval Latin word as the source, formed from debaten (“to debate”) and the Latin suffix -abilis.^[5][6] Dictionary.com derives it from Middle French.^[7]

Earliest recorded meaning

Of land on the border of two countries and claimed by both, especially the tract between England and Scotland: 1492, in a document printed in Rymer's Fœdera.^[2] The 1989 edition of the OED had dated this sense to 1453,^[8] and Etymonline notes that the border region was already called the Batable Landez in the mid-15th century.^[3]

Semantic evolution

The first uses concern disputed land, and the general sense "open to debate, questionable" followed in 1581, in Mulcaster's Positions;^[2][3] Merriam-Webster dates the word to 1536, in the territorial sense,^[5] and the Shorter Oxford dates both senses to late Middle English.^[4] From 1551 to 1568 the Debatable Land was used as a noun for the Anglo-Scottish border tract, and in the plural for the people who lived on it.^[2][9] Johnson (1755) defined the word as "disputable", quoting Hayward on the "debatable ground" by the Tweed.^[10] Chalmers applied it in 1814 to regions of thought.^[2] In Scots and Northumbrian dialect the phrase debatable land kept the old border sense, but it was obsolete by the time of the English Dialect Dictionary.^[11]
