Forms

seize (invariable)[1]

Etymology

It is inherited from Old French seze, inherited from Latin sēdecim (“sixteen”), a compound of sex (“six”) and decem (“ten”).[2][3][4] Old French also had seise (about 1220), and the present spelling is a remaking of about 1250.[3] Littré notes that the Latin word, stressed on its first syllable, gave the French form regularly.[5]

Cognate with Italian sedici, Old Occitan sedze, Catalan setze and Walloon saz.[6][5]

Earliest recorded meaning

It is first found as seze in Wace's Brut (about 1155), as the cardinal number “sixteen”.[2][3]

Semantic evolution

From its first records the cardinal number was also used as an ordinal, where modern French has seizième, as in la lune seze “the moon on its sixteenth day” (1165–1170), and as a noun.[3] The ordinal use after a name, as in Louis Seize, is dated 1792–1793 by the TLFi.[2] As a noun it names the sixteenth day of the month (1601, le seize juing), the number sixteen (1690) and a house numbered sixteen (1898).[2] In printing in-seize (1623) named a book format.[3] In cinema seize or 16 mm is a film gauge sixteen millimetres wide (1970).[2]
