From Latin nōnus (“ninth”). As a day of the Roman calendar, via nōnae (“ninth days”) from the original Roman practice of counting forward to the next full or new crescent moon, the nones' occurrence 8 days before the ides of every month (9 counting inclusively) following the establishment of a fixed calendar, and from the Latin practice of treating most recurring calendrical days as plurals. Some scholars believe the name is a variant of the nundines (nūndinae fēriae (“ninth-day festival”)), the Roman market days held every eight days (9 counting inclusively), which were likely announced for each coming month by the Roman kings on the first-quarter days. As a time of day, via the plural form of Middle English, Anglo-Norman, & French none and Latin nōna (“ninth hour”) after the manner of earlier matins, vespers, etc. As a meal, from the time of day, whether from its plural, genitive, or the occasional adverbial sense of -s.

The verb is derived from Middle English noselen (“to bend down”); further etymology uncertain, possibly: * a back-formation from noseling, noselyng (“on the back, supine; with the face downward, prone”, adverb), from nose (“nose”) (from Old English nosu, ultimately from Proto-Indo-European *néh₂s (“nose”)) + -ling, -lyng (suffix forming adverbs denoting direction, manner, or position); or * from nose (see above) + -el, -elen (diminutive or frequentative suffix) (in which case the English word is, by surface analysis, nose + -le (frequentative suffix)). Etymology 1, verb sense 2.3 (“to settle or lie comfortably and snugly”) is possibly influenced by nestle or nursle (frequentative of nurse). The noun is derived from the verb. Compare nozzle.

From Byzantine Greek ὠμοφόριον (ōmophórion), from Ancient Greek ὦμος (ômos, “shoulder”) + φέρω (phérō, “carry”).
