ἥττημα hēttēma

Defect, loss, defeat, or failure: a coming short. In Rom 11:12 τὸ ἥττημα αὐτῶν stands beside τὸ παράπτωμα αὐτῶν and is contrasted with τὸ πλήρωμα αὐτῶν. The noun can name a defeat or a loss; which shade Rom 11:12 takes is a question of context, not of the lexicon alone. The only other New Testament occurrence is 1 Cor 6:7, of a loss or defeat in going to law.
