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.

1. artĭo, īvi, ītum, 4, v. a. [1. artus], to fit close, to drive in tight (only ante-class.): surculum, Cato, R. R. 40, 3; so id. ib. 41, 2: linguam in palatum, Nov. ap. Non. p. 505, 30.

2. artĭo, īre, v. a. [ars], to indue with art; only in the two foll. exs.: artitus: bonis instructus artibus, skilled in arts. Paul. ex Fest. p. 17 Müll. (cf.: centum puer artium, Hor. C. 4, 1, 15).
Hence also endowed with cunning (cf. ars, II. fin.), artful: artiti viri, Plaut. As. 3, 2, 19 in varr. lectt.
