Choosing the right word Döderlein's Latin Synonyms

Consuetudo · Mos · Ritus · Cærimonia

Consuetudo denotes the uniform observance of anything as a custom, arising from itself, and having its foundation in the inclination or convenience of an individual or people, ἔθος; whereas mos (modus) is the habitual observance of anything, as a product of reason, and of the self-conscious will, and has its foundation in moral views, or the clear dictates of right, virtue, and decorum, ἦθος; lastly, ritus denotes the hallowed observance of anything, either implanted by nature as an instinct, or introduced by the gods as a ceremony, or which, at any rate, cannot be traced to any human origin. Consuetudines are merely factitious, and have no moral worth; mores are morally sanctioned by silent consent, as jura and leges by formal decree; ritus (from ἀριθμός, ῥυθμός), are natural, and are hallowed by their primæval origin, and are peculiar to the animal. (v. 75.) 2. Ritus is a hallowed observance, as directed and taught by the gods or by nature; whereas cærimonia (κηδεμονία) is that which is employed in the worship of the gods.

Origins

  1. Proto-Indo-European*leǵ-
  2. Proto-Indo-European*lḗǵs?
  3. Proto-Indo-European*legʰ-
  4. Proto-Indo-European*lḗgʰs?
  5. Proto-Italic*lēks
  6. Latinlēx

From Proto-Italic *lēks. The usual etymology derives the term from Proto-Indo-European *lēǵ-s, a root nomen actionis from *leǵ- (“to gather”), whence also legō. Palmer (1906) proposes an alternative origin in Proto-Indo-European *legʰ-s, root nomen actionis from *legʰ- (“to lie, to be in resting position”). Compare typologically English law, Russian уложе́ние (uložénije) from this PIE root. This alternative etymology is endorsed by Fortson.
