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.

commento, āvi, 1, v. act., collat. form of 1. commentor, q. v. (cf. Prisc. p. 797 P.), to delineate, sketch; only trop.: ora, humorously, qs. to demonstrate on the face, for to cudgel or beat, Plaut. Men. 5, 7, 30 dub. (Brix, commetavi; cf. 2. commeto).
Hence,

      1. b. commentātus, a, um, pass.: ut sua et commentata et scriptameminisset, Cic. Brut. 88, 301 (just before: secum commentatus in act. signif.): oratio, Q. Cic. ap. Cic. Fam. 16, 26, 1.
