The form seissid is the only attested inflected form. The trisyllabic forms shown in the table are expected to have undergone syncope and surface as *seiste (genitive singular feminine), *sestu (accusative/​vocative plural masculine), *sesta (nominative/​vocative/​accusative plural feminine/​neuter), *sestaib (dative plural), but these are not actually attested.
