A verb attested only in the form usaphda “he understood”, an aorist inflection with the 3rd person masculine pronominal prefix u- (SD/421). Archaically its aorist form underwent phonetic changes to become †saptha, but it was later reformed to be consistent with other inflections of the verb (such as the past tense ✱sapphada).
