Definition
An obsolete Latin term from old English law meaning to annul, make void, or reduce to nothing. To adnihilare a legal instrument, judgment, or proceeding was to treat it as having no legal force or existence — to hold it as nought.
The term functioned as a verb of negation in formal legal Latin, applied to proceedings, judgments, or acts that a court or authority declared entirely void rather than merely voidable or defective. The effect was absolute: the thing adnihilated was treated as if it had never existed.

Why It Matters in Research
ADNIHILARE is a term of historical interest rather than active legal currency. Researchers encounter it primarily in:
— Medieval and early modern English legal records and Year Books, where Latin pleading and Latin court language were standard.
— Writs, judgments, and chancery documents predating the English transition to English-language legal proceedings in the eighteenth century.
— Treatises and digests that cite or translate old Latin maxims, particularly those concerning the finality and stability of judgments.
The most practically significant context flagged in historical sources is the maxim reproduced in Burrill: judgments rendered in the king's court shall not be adnihilated (held for nought), but shall stand in their force until annulled by error or attaint. This maxim reflects a foundational principle of judgment finality — a doctrine very much alive today under the names res judicata and collateral estoppel, even though the Latin vocabulary has long since dropped away. A researcher tracing the historical roots of judgment finality doctrine may find ADNIHILARE and cognate terms bridging the conceptual gap between medieval English practice and modern preclusion doctrine.
The term should not be confused with adnullare (or annullare), which appears in the same maxim and carries a related but technically distinct meaning. Burrill's citation of the maxim distinguishes the two: adnihilari denotes treating a judgment as nothing informally or improperly, while adnullari refers to formal annulment through recognized legal process (error or attaint). This distinction matters when reading old Latin legal texts closely.
Researchers should also note that ADNIHILARE does not appear in modern legal usage and will not appear in contemporary statutory codes, regulations, or case law. Its presence in a source is itself a marker of age — useful for dating or contextualizing a document.

Historical Dictionary Support
All three source dictionaries agree on the core meaning: to annul, make void, reduce to nothing, treat as nothing, or hold for nought. The definitions are functionally identical across Black's first and second editions.
Burrill's entry is the most useful of the three. It supplies the Latin etymology (ad + nihil, meaning "to nothing"), which clarifies why the term means what it means, and it provides the only substantive illustrative text: the maxim concerning judgment finality in the king's court. That maxim is the term's most instructive historical context and the bridge to modern doctrine.
What the historical dictionaries do not supply: any discussion of how frequently the term appeared in actual practice, whether it was a term of art with precise procedural consequences distinct from adnullare, or what courts or instruments most commonly used it. Historical dictionary entries for terms like this tend to define without contextualizing. Burrill is the partial exception.
Neither Black's edition quotes any authority or case for the term's application, which reflects the broader limitation of early Black's entries on obsolete Latin terms — they translate but do not situate.

Jurisdictional Note
ADNIHILARE is a term of old English law and has no recognized counterpart in American statutory or common law as an active legal term. Its relevance is historical and comparative across jurisdictions that share roots in English legal Latin.
