Lewis & Short

Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.

Agnālĭa (com. Agōnālĭa, q. v.), ium, n., a Roman festival: Pars putat hic festum priscis Agnalia dictum, Una sit ut proprio littera dempta loco, Ov. F. 1, 325.

Ăgōnālĭa, ĭum or ōrum (like Saturnalia, Parentalia, etc.), n., a festival in honor of Janus, celebrated in Rome on the 9th of Jan. (V. Id. Jan.) and 21st of May (XII. Kal. Jun.).
Different derivations of the word were given by the ancients, concerning which see Ov. F. 1, 319-332. Ovid, in l. c., derives it from agonia, q. v. For other etym., v. the foll. art., and under agonium.
