Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
prŏfectīcĭus or -tĭus, a, um, adj. [proficiscor], that proceeds from some one (post-class.); profecticia dos est, quae a patre vel parente profecta est, de bonis vel facto ejus, Dig. 23, 3, 5, §§ 1, 6, 14; Ulp. Fragm. 6, 3; 4, 6.
