pacio
From LSJ
οἷς τὰ ὁρώμενα τὴν ἀρχὴν ἐνδίδωσι, καὶ οἷον ὑπήνεμα διὰ τῶν ὀφθαλμῶν τὰ πάθη ταῖς ψυχαῖς εἰστοξεύονται → who taketh his beginning and occasion from something which is seen, and then his passion, as though wind borne, shoots through the eyes and into the heart
Latin > English (Lewis & Short)
păcĭo: ōnis, f.,
I a contract, covenant (ante-class. for pactio): pacionem antiqui dicebant, quam nunc pactionem dicimus: unde et pacisci adhuc et paco in usu remanet, Fest. p. 250 Müll. (perh. too, ap. Fest. s. v. nuptias, p. 170, instead of ratio we should read pacio, acc. to the conject. of Dac. on the preced. passage).
Latin > French (Gaffiot 2016)
păcĭō, ōnis, f., c. pactio : Fest. 250.
