Definition
INITIAL has two distinct functions in legal contexts:
1. As an adjective: That which begins or stands at the beginning; pertaining to the first stage of a proceeding, relationship, or process. Used extensively in procedural law to designate the first in a sequence of required steps — initial appearance, initial pleading, initial determination, initial carrier.
2. As a noun (usually plural, initials): The first letter or letters of a person's name. A party may bind themselves to a written instrument by signing with their initials as effectively as by signing their full name. An initial standing between a given name and surname — a middle initial — is not legally considered part of the name itself; its omission or misstatement in a document does not generally affect validity.

Common Language
Modern common usage (Wiktionary): The first letter of a word or name, especially of a person's full names taken together; also, a large decorative letter opening a chapter or section.
Historical common usage (Webster's 1913): Of or pertaining to the beginning; marking the commencement; incipient. Placed at the beginning, standing at the head of a list or series.
The gap between common and legal meaning is narrow but consequential in two directions. First, the common understanding of initials as merely identifying shorthand understates their legal force: initials on a contract or instrument carry binding effect equivalent to a full signature. Second, the adjective form is far more doctrinally loaded in law than in everyday speech — "initial" in legal procedure designates a formal, triggering stage with defined rights and deadlines attached, not simply something that happens to come first.

Why It Matters in Research
The term operates at two very different registers in the Law Mind corpus, and conflating them will derail research.
As an adjective in procedure, "initial" is a term of art that attaches rights and deadlines. The initial appearance in criminal procedure is a constitutionally and statutorily significant event — it is not merely the first time a defendant appears but a formal proceeding with specific requirements. Researchers working in criminal, administrative, or veterans law should treat "initial [proceeding/determination/claim]" as a phrase with independent doctrinal weight, not as a generic temporal marker.
As a noun, the historical sources converge on two rules that remain practically relevant: (1) initials suffice for a binding signature; (2) a middle initial is not part of the legal name. The second rule has traps in historical records — discrepancies in middle initials across deeds, wills, and court filings were frequently litigated, and researchers tracing title or identity across old documents should not assume a middle initial mismatch is fatal, nor that it is insignificant without checking the jurisdiction's rule.
The "initial carrier" doctrine (carriers law / bailment) appears in the 2nd edition of Black's and was a significant issue in the interstate railroad era. Researchers in transportation law or 19th-century commercial litigation will encounter it in the corpus; it is now largely superseded by modern freight and carrier statutes but remains relevant to historical case research.
Administrative law researchers should note that "initial determination" or "initial decision" in agency proceedings is a term of art marking the agency's first-level ruling, from which administrative appeal rights flow. Missing that designation in a source document can cause a researcher to misread the procedural posture of a case.

Historical Dictionary Support
The four historical dictionaries are in close agreement on the noun usage. All four state the core rule — initials bind as effectively as a full signature — and cite the same New York authority (1 Denio 471). Burrill and Rapalje both note the middle-initial rule (not part of the legal name), citing Pennsylvania and New York authority. Black's 2nd edition is the only source to treat the compound term "initial carrier," reflecting the late-19th-century emergence of through-routing disputes in railroad law; the 1st edition omits it entirely.
What the historical sources collectively miss is the procedural adjective usage that now dominates legal writing. None of the four dictionaries address "initial appearance," "initial pleading," or "initial determination" as terms of art — a natural gap given that much of modern administrative and criminal procedure developed well after these dictionaries were compiled. Researchers relying solely on these sources for the adjective sense will find them unhelpful; the procedural meaning must be traced through modern rule-based sources.
Burrill's note that "initials is now a common word" reflects the mid-19th-century moment when the term was transitioning from legal shorthand into general usage — a useful marker for researchers trying to date when a document's author was using the term in a technical versus colloquial sense.

Jurisdictional Note
The rule that initials constitute a valid signature is broadly accepted across American jurisdictions, but specific statutes governing electronic signatures, wills, and deeds may impose additional formalities that override the common-law rule. The middle-initial rule (not part of the legal name) is similarly widespread but was and remains subject to local variation, particularly in probate and real property contexts.
