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 abiuro could not be parsed. Trying a normal dictionary lookup:
ab-jūro, āvi, ātum, 1, v. a. (abjurassit for abjuraverit, Plaut. Pers. 4, 3, 9), to deny any thing on oath: rem alicui. ne quis mihi in jure abjurassit, Plaut. Pers. 4, 3, 9: pecuniam, id. Rud. prol. 14: creditum, Sall. C. 25, 4.
Absol., Plaut. Curc. 4, 2, 10; cf.: mihi abjurare certius est quam dependere, * Cic. Att. 1, 8, 3.
Poet.: abjuratae rapinae, abjured, denied on oath, Verg. A. 8, 263.
