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

From Proto-Italic *mōs, a root noun interpreted as an s-stem noun, of uncertain origin. Generally believed to derive from Proto-Indo-European *moh₁-, *meh₁- (“to intend or be intent upon, to be of strong will”) (though the more common meaning of “to measure” may be the original, with “to intend” as a semantic extension), whence Ancient Greek μαίομαι (maíomai, “to strive”) and perhaps Ancient Greek Μοῦσᾰ (Moûsă, “Muse”), and also English mood. It has also been conjectured that some senses of mōs, such as those having to do with “manner” and “way”, may indicate a possible derivation from Proto-Indo-European *med- (“to measure”), compare and contrast modus; if that is true, it would seem to suggest an example of combined etymology or conflation. If two such roots *med- and *meh₁- existed, both meaning “to measure”, it is plausible that the latter was derived from the former via early PIE glottalic *d ~ *h₁ alternation, seen for example in the pair *dwi- : *h₁wi- (“in two; apart”) and possibly in other roots such as *wed- : *weh₁- (“to wet; water”); *h₂ed- : *h₂eh₁- (“to dry (by fire)”).
