Choosing the right word Döderlein's Latin Synonyms

Margo · Ora

Margo (ἀμέργων) denotes the brink, the natural boundary of a surface, considered almost as a mere mathematical line, and only improperly as including an exterior portion of the surface; whereas ora (ὤα, οὖρος, ὅρος) denotes the brim, or border, the artificial edging of a surface, generally for the sake of ornament, and therefore necessarily including a certain portion of the surface. Hence we say, ora togæ, but not margo; and, on the other hand, margo fluminis and ripæ, if the mere line of shore is meant, without any portion of the bank. (iii. 212.)

Ripa · Litus · Ora · Acta

1. Ripa (ῥιπή, ἐρείπω,) is the bank of a river, like ὄχθη; whereas litus, ora, acta, the shores of the sea. Mela. lii. 9. Oras ad Eurum sequentibus nihil memorabile occurrit; vasta omnia vastis præcisa montibus ripæ potius sunt quam litora: and iii. 3, 4. i. 2, 2. Vitruv. ii. 9, 14. Circa ripam fluminis Padi et litora maris Adriatici. Colum. i. 5. Ovid, Met. i. 42. 2. Litus denotes the shore only as the line which separates the land from the sea, as the strand, like ἠϊών and ῥηγμίν; whereas ora and acta, as the space and tract of land that borders on the sea, as the coast, like ἀκτή and αἰγιαλός; ora (ὤα, οὖρος,) only in geographical reference to the adjacent land, in opp. to the inland country; but acta (ἀκτή) with the accessory notion of being distinguishable by the senses, inasmuch as the coast affords striking views and a pleasant residence. Liv. xxiv. 8. Classem paravimus ut Africæ oram popularemur, ut tuta nobis Italiæ litora essent. Plin. Ep. v. 6, 2. Gravis et pestilens ora Tuscorum, quæ per litus extenditur. Hence litoris ora, that is, ora per litus extensa, Virg. G. ii. 44. Tac. Ann. ii. 78. Appul. Met. iv. p. 92. Avian. Fab. xx. 10.—And Prudent. adv. Symm. iv. 136. Invenit expositum secreti in litoris acta. Cic. Fam. ix. 6. Ea tractes quorum et usus et delectatio est omnibus illis actis et voluptatibus anteponenda. Acta is a foreign word of Greek extraction, which Tacitus (Hist. iii. 76.) expresses by the circumlocution amœna litorum. (iii. 207.)

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.)
