Adnihilare

Lat. [from ad, to, and nihil, nothing.] To reduce to nothing; to treat as nothing; to hold as, or for nought. Judicia in curia regis reddita non adnihilentur, sed stent in suo robore quousque per errorem aut attinctam adnullentur; judgments rendered in the king's court shall not be held for nought, but shall stand in force until they be annulled by error or attaint.

2 Inst. 360.

Adnichile is used in the statute 28 Hen. VI.
