Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
The word reiectaneus could not be parsed. Trying a normal dictionary lookup:
rējectānĕus, a, um, adj. [reicio], that is to be rejected, rejectable (a word formed by Cic. as a philosoph. t. t.): morbum, egestatem, dolorem non appello mala, sed si libet, rejectanea (as a transl. of the Stoic ἀποπροηγμένα), Cic. Fin. 4, 26, 72 (cf. rejecta, id. ib. 3, 16, 52; and reicienda, id. ib. 5, 26, 78; and reducta, q. v.).
