This adverb means "still," "yet," or "even now," emphasizing the continuation of a situation or the surprising persistence of a state. Classical usage indicated something happening just at that moment or continuing even then. Jesus uses it in Matthew 15:16 expressing mild exasperation with the disciples: "Are you still without understanding?" The adverb emphasizes the unexpected persistence of their dullness—after all Jesus' teaching and miracles, are they yet failing to comprehend? The question implies they should have progressed beyond this point; their continued lack of understanding is surprising and disappointing.
