peninsular

Etymology

It is formed from English peninsula + -ar,^[2][3][4] perhaps after French péninsulaire.^[5][3] The OED notes that the French word is recorded once as a noun, "inhabitant of a peninsula", in Middle French in 1556, and otherwise only from 1834.^[2] The base noun comes from Latin paeninsula (“peninsula, literally almost an island”),^[3][2][4] from paene (“almost”) and insula (“island”).^[3][6][2]

Earliest recorded meaning

Of, relating to, or having the nature of a peninsula: before 1613, in a work by E. Brerewood on languages and religions, printed in 1614.^[2][7] Etymonline dates the word to the 1610s,^[3] and the Shorter Oxford to the early 17th century.^[5]

Semantic evolution

From 1811 the adjective was used, usually with a capital, of the Iberian peninsula, Spain and Portugal,^[2][5][7] above all in Peninsular War, the campaigns of 1808–14 in which British and allied forces, largely under Wellington, drove the French out of the peninsula.^[3][5] Etymonline notes the American Peninsular Campaign of 1862, the Army of the Potomac's failed advance on Richmond up the peninsula between the Rappahannock and James rivers.^[3] The noun, a native or inhabitant of a peninsula, especially of the Iberian one, is recorded from 1854,^[2][7] and a soldier of the Peninsular War was briefly called a Peninsular (1888).^[2] Merriam-Webster Unabridged also records the capitalized adjective for what is characteristic of Iberia.^[4]
