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 subiectivus could not be parsed. Trying a normal dictionary lookup:
subjectīvus, a, um, adj. [subjectus], of or belonging to the subject of a proposition, subjective: pars, i. e. the subject, App. Dogm. Plat. 3, p. 30, 30; Mart. Cap. 4, § 393; Tert. Virg. Vel. 4 fin.
Adv.: subjectīvē, subjectively, Mart. Cap. 4, § 393.
