Definition
An adjective of priority, sequence, and preference. In legal usage, "first" carries one or more of three distinct senses depending on context:
1. Sequential or ordinal priority: Preceding all others of the same kind or class in numerical or chronological order. Used in compounds such as first mortgage, first purchaser, first occupant, and first taker to designate the party or instrument that holds temporal or numerical precedence over competing claims of the same type.
2. Preferential or superior rank: Entitled to priority or preference above others, not merely as a matter of sequence but as a matter of legal right. A first mortgagee, for example, holds not just earlier-in-time status but a superior lien position enforceable against subsequent encumbrancers.
3. Chief or most eminent: Leading or highest in importance or authority. This sense appears in constitutional and institutional contexts — First Amendment, First Circuit, first reading — where "first" denotes rank or hierarchy rather than time.
A fourth, narrower sense applies specifically in testamentary construction: when "first" appears in a will, courts have held that it does not necessarily import precedence of one bequest over another. The word in that context is more likely descriptive than operative.

Common Language
Modern common usage (Wiktionary): Preceding all others of a series or kind; the ordinal of one; earliest. Most eminent or exalted; most excellent; chief; highest.
Historical common usage (Webster's 1913): Preceding all others of a series or kind; the ordinal of one; earliest. Foremost; in front of, or in advance of, all others. Most eminent or exalted; most excellent; chief; highest.
The common and legal meanings align closely in ordinary usage, but the gap emerges in two specific legal contexts. First, in property and secured transactions law, "first" carries enforceable legal consequences — a first mortgage is not simply the earliest in time but the senior lien as a matter of law, with priority rights that cannot be undone merely by a later agreement between junior parties. Second, in testamentary construction, courts have refused to give "first" its intuitive common meaning of sequence or preference, treating it as surplusage unless clear contextual evidence supports a priority reading.

Common Confusion
"First" as sequence versus "first" as priority. These are related but not identical. In a race-notice or notice jurisdiction recording system, the party who records first in time is not automatically the party with first-lien priority — intervening notice, fraud, or failure to record can displace temporal sequence. Researchers conflating chronological firstness with legal priority will misread title chains and lien-priority disputes. Similarly, a first endorser on a negotiable instrument is first in sequence but may not be first in liability depending on the instrument's structure.

Why It Matters in Research
"First" is one of the most heavily compounded adjectives in legal texts, and its meaning shifts depending on the compound. Researchers must identify which sense is operative in any given source:
Lien and mortgage priority research: Historical sources use "first mortgage" to mean senior lien, but the legal mechanics behind that priority — recording statutes, equitable subrogation, purchase-money priority — varied considerably by jurisdiction and era. Pre-twentieth-century cases may assume a race system that has since been replaced by race-notice in the same jurisdiction. Do not import modern priority rules into nineteenth-century lien disputes without checking the applicable recording act.
Testamentary construction: The Bouvier and Anderson entries both flag the Maine cases on point — courts refusing to read "first" as establishing bequest priority. This is a narrow but genuine trap. A will that says "I give first to my son, and then to my daughter" may not create enforceable priority between those gifts if the estate is insufficient. Historical probate research will encounter this construction frequently.
Bills of exchange: "First of exchange" refers to the first of a set of bills drawn in duplicate or triplicate, a practice common in international commercial law through the nineteenth century. The term appears regularly in pre-twentieth-century commercial cases and treatises. Researchers unfamiliar with the set-of-exchange practice will misread these instruments entirely.
Constitutional compounds: "First Amendment" and related terms are treated as proper nouns in the corpus and have their own dedicated research pathways. Do not conflate "first" as a priority adjective with "First" as a constitutional designation.
Anderson's note about presidential rulemaking authority appearing mid-entry reflects a transcription artifact from the source volume and is not part of the legal definition of "first."

Historical Dictionary Support
Anderson and Black agree on the core meaning: sequential precedence plus preferential legal status, with Black adding the gloss of "entitled to priority or preference above others" — language that links firstness to enforceable legal rights rather than mere chronology. Both sources treat "first" primarily as it functions in compound legal terms rather than as a standalone word.
Bouvier focuses almost exclusively on the testamentary construction problem, citing two Maine cases for the proposition that "first" in a will does not necessarily establish bequest priority. This is the most legally consequential divergence from ordinary meaning in the historical record, and Bouvier correctly flags it as a standalone caution rather than burying it in the general definition.
Black's entry opens with the maxim Firmior et potentior est operatio legis quam dispositio hominis — "the operation of law is firmer and more powerful than the disposition of man" — which, while genuinely appearing in the source volume at that page location, is a typographical artifact of how the second edition was compiled. It is not definitionally connected to "first" and should not be read as interpretive context for the term.
What all three historical sources underemphasize: the relationship between "first" and recording-act priority, which became increasingly important through the nineteenth and twentieth centuries as American land title systems matured. Modern researchers will find this gap most acute when working with pre-codification property disputes.

Jurisdictional Note
Priority meaning of "first" in property contexts depends heavily on whether the jurisdiction follows a race, notice, or race-notice recording statute — a variation that is not reflected in the historical dictionary definitions, which treat first-in-time as a largely self-executing rule. In race-notice jurisdictions, being "first" to record matters only in combination with lack of notice, significantly complicating what the historical sources present as a straightforward priority determination.
