Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
prae-ordĭno, āre, 1, v. a., to preordain (eccl. Lat.): Deus praeordinavit te, ut, etc., Vulg. Act. 22, 14.
Hence, praeordĭnā-tus, a, um, Part., ordered beforehand, preordained (post-class.): causae, Cael. Aur. Acut. 1, 4, 44; Vulg. Act. 10, 41.
