cerno, crēvi, crētum (part. pass. cretus is apparently used only once: cineris bene creti, Pall. 12, 22, 3; but freq. in the compounds of cerno; for the simple part., the orig. form certus also is very rarely used: certā deinde sorte senatus consultum factum est, Liv. 36, 2, 2; v. under II. C., and cf. certus), 3, v. a. [root car- for scar-, to separate; cf. κρίνω; hence, σκώρ, stercus, screo; cf. cera].
I To separate , sift (rare): per cribrum, Cato. R. R. 107, 1: farinam cribro, Plin. 18, 11, 29, § 115; cf. id. 33, 5, 26, § 87; Pall. Jun. 1; Veg. 3, 28, 6: in cribris omnia cerne cavis, Ov. Med. Fac. 62; cf.: per densa foramina, id. ib. 89: cineris bene creti, well sifted , Pall. Nov. 22.—Far more freq.,

Enn. ap. Varr. L. L. 6, § 81 Müll.; 7, § 76 ib.: sed quis illic est, procul quem video? estne hic Hegio? si satis cerno, is hercle'st, Ter.

Tusc. 1, 20, 46: quae cernere et videre non possumus, id. de Or. 3, 40, 161; cf. id. Rep. 6, 20, 21 sq.: ego Catuli Cumanum ex hoc loco cerno, Pompeianum non cerno, id.

Timo l. 2, 2. —Ante-class., of the hearing: vox illius certe est: idem omnes cernimus, Att. ap. Non. p. 261, 11, and perh. also, Titin. ap. Prisc. p. 898 P.—Hence,
