Etymology

The noun is derived from Late Middle English meridian, meridien (“midday, noon; position of the sun at noon; the south; longitude of a place; (astronomy) celestial meridian”) [and other forms], from Anglo-Norman meridien (“midday”), Middle French meridien (“midday; the south; terrestrial meridian; (astronomy) celestial meridian”) (modern French méridien), and Old French meridiane, meridiiene, and from their etymon Latin merīdiānum (“midday; position of the sun at noon; the south”), a noun use of the neuter form of merīdiānus (“relating to midday; southern”); see further at etymology 1. Sense 1.1 (“celestial meridian”) is ultimately modelled after Latin merīdiāna līnea (“meridian line”). Sense 5.2 (“midday rest; siesta”) is modelled after Late Latin meridiana (“midday; midday rest”), probably short for Latin merīdiāna hōra (“midday time”). The verb is derived from the noun.
