“favorable” in Latin

Of persons and personified objects, favens alicui: studiosus alicujus: benevolus alicui or in aliquem (with the same difference as the substantives in FAVOR): amicus alicui (amicably or favorably disposed toward anybody): propitius (of the gods, and also of a superior toward his inferior, though less common in this case): ☞ propensus and pronus, in the Golden Age, only denote inclination toward anything, but not predilection for a person, as in Tac., etc. To be favorable to anybody, alicui favere; favore aliquem complecti; alicujus esse studiosum: favorable sentiments toward anybody, propensa in aliquem voluntas.

Of things (corresponding with views, wishes, design, etc), faustus (as an effect of divine favor; e.g., a day, omen, etc.). (The words are found in this connection and order.) faustus felixque: dexter (litterally, on the right hand; of favorable omens; of birds, etc.): secundus (the proper word, of a favorable wind; then, general term, for what goes according to one’s wishes; a battle, circumstances, an event, etc.): prosper (of what fulfills one’s hopes and wishes; e.g., progress, event, consequence of an undertaking, return, circumstances, etc.): commodus (fit, convenient): idoneus (suitable for a certain purpose): opportunus (favorably situated with reference to place; then also with reference to time). (The words are found in this connection and order.) opportunus atque idoneus: aequus (convenient; of place and time; opposed to iniquus; mostly, but not always, attended by a negative; Vid: Caes., B. C. 1, 85; ☞ Suet., Caes., 35). ☞ A possessive pronoun (meus, tuus, suus, etc.) is often sufficient to express “favorable;” e.g., to fight under favorable circumstances or auspices, suo Marte or sua fortuna pugnare. I am fighting on favorable ground, or in a favorable position, meo loco pugnam facio. Favorable circumstances, res secundae, prosperae (with reference to fortune, etc.); opportunitas temporis, tempus opportunum (times or circumstances that will favor anything, or be favorable to anything, εὐκαιρία): favorable wind, ventus secundus, or prosper, or idoneus: to set sail with a favorable wind, ad occasionem aurae evehi (Suet., Oct., 87): favorable weather, idonea tempestas (e.g., ad navigandum): favorable season or time of the year, idoneum or commodum anni tempus: a favorable place, ground, or spot (e.g., for fighting a battle), locus opportunus, or idoneus, or opportunus atque idoneus; locus aequus: the ground or place, as well as the time being favorable, et loco et tempore aequo: he did not consider the ground favorable for his army, non aequum locum videbat suis.
