Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
nŏvātor, ōris, m. [novo], a renewer, restorer (post-class.): verborum, i. e. who brings obsolete words again into use, Gell. 1, 15, 18: stirpis Anniae, Aus. Ep. 16, 32.
