Definition
PRIOR functions in legal usage primarily as an adjective meaning earlier in time, superior in rank, or preferred in right. It also appears as a noun in two distinct senses. Context determines which meaning applies.
1. As adjective (the dominant legal usage): Coming before in time or order; having precedence or superior rank as a matter of law. A prior lien is one that attaches before a competing lien and therefore takes precedence in enforcement. A prior judgment is one rendered before the matter currently at issue and may carry res judicata or collateral estoppel effect. A prior inconsistent statement is one made before trial that contradicts a witness's current testimony. Priority of right—who stands first in line to collect, to claim, or to enforce—depends entirely on which interest is "prior."
2. As noun (historical ecclesiastical usage): The chief of a religious convent, ranking next below an abbot. This meaning survives in historical legal sources addressing church property, ecclesiastical corporations, and early English land grants, but has no application in modern secular legal practice.
3. As noun (criminal law shorthand): In modern criminal practice and colloquial usage, "a prior" or "priors" refers to a defendant's prior convictions or prior criminal record. This usage is common in sentencing proceedings, habitual offender statutes, and criminal background discussions, though formal pleadings and opinions typically use "prior conviction" or "prior offense" in full.

Common Language
Modern common usage (Wiktionary): Wiktionary treats "prior" primarily as a surname or a geographic reference, reflecting how thoroughly the adjective sense has become invisible as a standalone headword in general dictionaries.
Historical common usage (Webster's 1913): "Preceding in the order of time; former; antecedent; anterior; previous; as, a prior discovery; prior obligation."
The common adjective sense in Webster's 1913 maps closely onto legal usage, but legal sources extend "prior" into a term of art with normative weight: in law, being prior does not merely describe sequence—it establishes enforceable superiority of right. A prior lien is not just earlier; it is legally preferred. That normative dimension is absent from the ordinary meaning and accounts for the bulk of the term's legal significance.

Common Confusion
Three contexts generate recurrent confusion:
First, researchers conflate "prior" (adjective establishing temporal or rank superiority) with "previous" in contexts involving prior art, prior restraint, and prior inconsistent statements. These are each terms of art with their own doctrinal frameworks—do not assume that "prior" in one context carries the same legal freight as "prior" in another.
Second, the criminal-practice shorthand "priors" (meaning prior convictions) is distinct from the procedural concept of a "prior proceeding." A defendant's priors affect sentencing enhancement; a prior proceeding may trigger double jeopardy, claim preclusion, or issue preclusion. These are unrelated doctrines reached through the same word.
Third, in older sources, PRIOR as a noun (the ecclesiastical officer) can cause genuine confusion when reviewing early English property records or church corporation cases. A conveyance "to the Prior of [institution]" is a grant to an ecclesiastical officeholder, not a description of precedence.

Why It Matters in Research
Priority is one of the organizing principles of private law. The maxim carried in Black's 2nd Ed.—prior tempore potior jure ("he who is first in time is stronger in right")—runs through lien law, secured transactions, recording acts, bankruptcy distribution, and intellectual property. Researchers should treat "prior" not as a neutral timestamp but as a legal conclusion that something ranks ahead of something else.
Navigational traps in the corpus:
Recording acts invert the common-law default. Under race, notice, and race-notice statutes, a later-recorded interest can defeat a prior-in-time interest. Corpus sources from different periods and jurisdictions will say contradictory things about whether "prior" means "wins"—because sometimes it does not.
"Prior art" in patent law and "prior restraint" in First Amendment law are each sufficiently developed doctrines that searching the corpus for "prior" alone will surface irrelevant results. Filter by doctrinal area.
Criminal sentencing materials use "prior" heavily in the context of enhancement statutes. Pre-guidelines federal materials, state three-strikes materials, and habitual offender provisions each define "prior conviction" differently—particularly on questions of whether juvenile adjudications, foreign convictions, or vacated convictions count. The word is the same; the definition varies by statute and jurisdiction.
The ecclesiastical noun sense appears in pre-nineteenth-century English property and corporation materials. Researchers working in that period should not assume "prior" is functioning as an adjective.

Historical Dictionary Support
Black's 1st Ed. records only the noun sense (the ecclesiastical officer), treating "prior" as a proper subject for a legal dictionary entry solely because of its role in church and convent governance—reflecting the heavily English ecclesiastical law heritage of early American legal dictionaries.
Black's 2nd Ed. is substantially more complete. It supplies the Latin form (prior petens, meaning the person first applying), gives the adjective definition with its key legal applications (lien, mortgage, judgment), and preserves the maxim prior tempore potior jure. This edition recognizes that the adjective is the term's primary legal value. The case citation to Fidelity, etc., Safe Deposit Co. v. Roanoke Iron Co. illustrates lien priority in a secured creditor context.
Anderson's Dictionary of Law does not address "prior" directly; the entry retrieved under this search concerns "print" and copyright—a retrieval artifact, not relevant content.
No historical dictionary adequately covers the modern criminal-law usage of "priors" as a noun of art for prior convictions. That usage developed primarily through twentieth-century sentencing practice and is absent from all three shelf sources. Researchers relying solely on historical dictionaries will miss this entirely.

Jurisdictional Note
Priority rules vary significantly by subject matter and jurisdiction. In real property, priority among competing interests is governed by state recording acts, which differ in type (race, notice, race-notice) and definition of what qualifies as constructive notice. In bankruptcy, federal law governs priority of distribution among creditors under 11 U.S.C. § 507, displacing state priority rules. In criminal sentencing, what counts as a "prior conviction" for enhancement purposes is defined separately by each jurisdiction's statutes and may turn on the date of conviction, date of offense, or date of sentence.
