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.

in-sterno, strāvi, strātum, 3, v. a.

  1. I. To cover, cover over: instrata cubilia fronde, Lucr. 5, 987; so, instratos ostro, Verg. A. 7, 277; cf.: si palo adacto caverna paleā insternatur, Plin. 19, 5, 26, § 84: pontes altos, Verg. A. 12, 675.
    1. B. Transf., to lay upon as a cover, to spread over: modicis instravit pulpita tignis (dat.), laid the stage over an insignificant scaffolding, Hor. A. P. 279.
  2. II. To cast or throw into: sese Ignibus, Stat. Th. 12, 800.

instrātum, i, n. [insterno], a covering (ante- and post-class.), Cato, R. R. 10, 3; Dig. 50, 16, 45.

* 2. in-strātus, a, um, adj. [2. insterno], not covered or spread over: cubile, an unspread couch, Verg. G. 3, 230 (so interpp. plur. ad loc.; but it is better to construe instrato as part. of insterno, with frondibus hirsutis; cf.: instrata cubilia fronde, Lucr. 5, 987 Wakef. ad loc.).
