Forms
mœurs f pl (plural only)[1] Old French murs (about 1112), mors (about 1155) and meurs (13th century); mœurs from the 14th century.[2][3] Anglo-Norman also had moers, mours and morz.[4]
Etymology
It is inherited from Latin mōrēs (“ways, character, morals”), the plural of mōs.[5][6][7][1] In Latin the noun was a way of acting fixed by custom rather than by law, and also meant “character”; through written Latin the word owes part of its senses to Ancient Greek ἦθος (êthos).[6][7][8] The Latin noun was masculine;[6][7] French made it feminine, though it is found as a masculine again in the 16th century.[6][7]
Among the Romance languages it passed only into French and Old Occitan mors.[6][8] Rey notes that the Latin word may be Indo-European but has a counterpart only in Irish.[6]
Earliest recorded meaning
It first appears early in the 12th century in Benedeit's Voyage of Saint Brendan, meaning a way of behaving, conduct judged as good or bad: Murs out bons cil ermite e sainte vitte “those hermits had good ways and a holy life”.[5]
Semantic evolution
The first sense was conduct seen in the light of good and evil, in bones mors (1155) and mals murs (about 1175), whence bonnes and mauvaises mœurs;[5][6] avoir des mœurs meant “to have good morals” from 1718.[5][6] A more neutral sense, the habits and way of life of a group, appears about 1265 in les meurs et les us, was applied to whole peoples from 1549 and, in classical usage, to good manners (1688).[5][6]
From the 16th century the word was used of the habits of animal species, and in 18th-century criticism of what suits the characters, times and places shown in a literary work (1701).[6] Police des mœurs (1890), the vice squad dealing with prostitution, gave the elliptical les mœurs (1876).[6] English borrowed the word as moeurs by 1922.[9]

Usage notes
The final -s was traditionally silent; the pronunciation /mœʁs/, frowned on in careful speech but now common, comes from the spelling, helped by the word's lasting contact with written Latin.[6][7][12] The word is used only in the plural.[1][8]
