Choosing the right word Döderlein's Latin Synonyms

Facies · Os · Vultus · Oculi

Facies (from species) and oculi (from ὄκκος) denote the face and eyes only in a physical point of view, as the natural physiognomy and the organs of sight; but os and vultus with a moral reference, as making known the temporary, and even the habitual state of the mind by the looks and eyes; os (from ὄθομαι), by the glance of the eye, and the corresponding expression of the mouth; vultus (from ἑλικτός), by the motion of the eye, and the simultaneous expression of the parts nearest to it, the serene and the darkened brow. Tac. Agr. 44. Nihil metus in vultu; gratia oris supererat. (iv. 318.)

Origins

Proto-Indo-European *h₃ekʷ-der. Proto-Indo-European *-lós Proto-Indo-European *-elós Proto-Italic *-elos Latin -ulus Latin oculus De Vaan reconstructs Proto-Italic *okʷ(e)los m or *okʷ(e)lom n, ultimately from an uncertain descendant of the Proto-Indo-European root *h₃ekʷ- (“to see; eye”) suffixed with -ulus (from Proto-Italic *-elos, from Proto-Indo-European *-lós). Witczak 2021 argues it was originally a neuter diminutive, whereas Sen 2015 sees it as an agent noun formation. Compare the gender of the cognates Sanskrit अक्षि n (ákṣi, “eye”) and Ancient Greek ὄσσε n (ósse, “eyes”) and ὤψ f (ṓps, “eye”). If the noun was originally neuter, then the masculine nominative singular oculus may be a back-formation from an original neuter dual form oculī (reinterpreted as a masculine nominative plural), as proposed by Alan Nussbaum. For other survivals of the second-declension neuter dual ending, see also the masculine-like plurals of caelum (“sky”), frēnum (“bridle”), and rāstrum (“rake”).
