Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
sŭperlātīvus, a, um, adj. [superlatus];
- I. in gram.: nomen, superlative, in the superlative degree, Charis. p. 87 P.; Prisc. p. 605 ib.
- II. Hyperbolic, exaggerated: sententiae, Isid. 2, 21, 16.
Hence, adv.: sŭperlātīvē, superlatively, in the superlative, Charis. p. 87 P.
