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 coniugialis could not be parsed. Trying a normal dictionary lookup:
conjŭgĭālis, e, adj. [conjugium], belonging to marriage, conjugal, connubial (perh. only in Ov.): foedus, Ov. M. 11, 743: festa, id. ib. 5, 3: jura, id. ib. 6, 536.
