In Jainism, an abhavi (more commonly written abhavya) is a soul that is incapable of attaining moksha. In simple words, such a jīva does not have the spiritual potential to become liberated in this cycle of existence. ( jainknowledge.com)

The opposite is bhavya, meaning a soul that does have the capacity for liberation. Jain sources describe bhavya and abhavya as states related to a soul’s spiritual potential. ( jainknowledge.com)
