G0208–ἀκυρόω–akuroō

And honor not his father or his mother, he shall be free. Thus have ye made the commandment of God of no effect by your tradition.

ἠκυρώσατε ēkurōsate “you made void”

Making the word of God of no effect through your traditions, which ye have delivered: and many such like things ye do.

ἀκυροῦντες akurountes “making void”

And this I say, that the covenant that was confirmed before by God in Christ, the law, which was four hundred and thirty years after, cannot disannul, that it should make the promise of no effect.

ἀκυροῖ akuroi “does annul”
