past participle (accusative singular neuter) of viññāti,
Analysis. vi + ññā + ta: vi- (apart, clearly) + √ñā (know) + -ta (past participle suffix). The prefix vi- adds clarity and distinctness to the root meaning of knowing.
Etymology. √ñā (to know) is cognate with Sanskrit jñā and Proto-Indo-European *gn-eh₂- (know), seen in English "know," Latin "gnosco," and Greek "gignōskō." The prefix vi- (apart, asunder, with intensive clarity) sharpens the sense of knowing into discerning or recognizing clearly.
