Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
consĭlĭōsus, a, um, adj. [consilium], full of prudence or wisdom, considerate, etc., a word formed, acc. to Gell. 4, 9, 12, by Cato (mostly post-class.): exempla, Fronto, Ep. ad Ver. 1 (in imitation of Cato).
