Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
pōdex, ĭcis, m. [perh. for pordex, from pedo, ere], the fundament, anus, Hor. Epod. 8, 6: lēvis, Juv. 2, 12.
pŏdĭcus, a, um, adj. [ποῦς], of or belonging to a foot (post-class.): sed temporum alia simplicia sunt, quae podica etiam perhibentur. Pes veri est numeri prima progressio, Mart. Cap. 9, § 974.
