Definition
In legal usage, *definite* means fixed, certain, bounded, and determinate — capable of being ascertained with precision rather than left to inference, approximation, or future resolution. The term appears across legal contexts as a qualifier of sufficiency: a term, obligation, description, or period is legally operative when it is definite, and legally deficient when it is not.
The concept most frequently arises in the following contexts:
1. CONTRACT TERMS: A contractual provision — particularly a price, quantity, duration, or subject matter — must be sufficiently definite to be enforceable. A court cannot supply essential terms that are absent or too vague to admit of a fixed meaning.
2. LEGAL DESCRIPTIONS: In property law, a deed or conveyance must contain a definite description of the land conveyed. A description that cannot be located on the ground with reasonable certainty may void the instrument or render it unenforceable.
3. SENTENCES AND PERIODS: A *definite* sentence or term of imprisonment is one with a fixed endpoint — a specified number of months or years — as opposed to an indeterminate sentence whose duration depends on administrative or parole-board discretion.
4. OBLIGATIONS AND CONDITIONS: An obligation is definite when the duty it imposes can be identified without ambiguity. A condition is definite when its occurrence or non-occurrence can be determined objectively.

Common Language
Modern common usage (Wiktionary): Having distinct limits; free from any doubt; determined; resolved; designating an identified or immediately identifiable person or thing.
Historical common usage (Webster's 1913): Having certain or distinct limits; determinate in extent or greatness; limited; fixed. Having certain limits in signification; determinate; certain; precise; exact; clear.
The gap between common and legal meaning is narrow but consequential. In ordinary speech, *definite* functions as a modifier describing clarity of thought or intention — "I have a definite answer." In law, it is a threshold standard of enforceability. A term may seem clear to the parties while still failing the legal definiteness test if a court cannot objectively determine its content without speculation. The word's common meaning thus understates the evidentiary and analytical burden the legal standard imposes.

Common Confusion
DEFINITE vs. CERTAIN: These terms are used interchangeably in both historical dictionaries and many courts. The distinction, where courts draw one, is that *certain* often refers to the fact of an obligation's existence (it will arise), while *definite* refers to the precision of its content (its terms can be ascertained). In practice, many opinions treat them as synonyms.
DEFINITE vs. SPECIFIC: *Specific* in legal usage typically modifies performance (specific performance) or intent (specific bequest). *Definite* addresses ascertainability and precision of terms. A specific obligation is one directed at a particular object; a definite obligation is one whose terms are fixed enough to be enforced.

Why It Matters in Research
The primary research trap with *definite* is that it is rarely the operative legal term of art in modern doctrine — modern courts often restate the same requirement as "sufficiently definite," "definite and certain," or "not too indefinite to be enforced," absorbing the concept into a broader discussion of enforceability or vagueness. Researchers searching only for the word *definite* will miss much of the relevant doctrine. Search also for *definiteness*, *certainty of terms*, *indefiniteness*, and *vagueness* depending on the context.
In contract law research, *definite* connects directly to the offer doctrine. For a communication to constitute a legally operative offer, its terms must be sufficiently definite to permit the conclusion that mutual assent has occurred and to allow a court to frame a remedy for breach. Historical sources, including Bouvier's, treat this requirement as implicit in the nature of contract rather than articulating it as a formal rule. Modern contract doctrine — including the UCC's gap-filling provisions — has substantially relaxed the definiteness requirement for commercial sales contracts, meaning pre-UCC sources overstate the strictness of the standard in commercial contexts.
In property research, *definite description* requirements are highly jurisdiction-specific and fact-intensive. A description treated as sufficiently definite in one jurisdiction may not satisfy another's standard.
In criminal sentencing research, the distinction between *definite* and *indeterminate* sentences is fundamental to understanding prison reform, parole eligibility, and sentencing guideline regimes. Many states moved from indeterminate to definite (or determinate) sentencing structures during the late twentieth century; historical sources reflecting pre-reform law will describe a system that has been substantially modified or abolished in many jurisdictions.
Anderson's Dictionary of Law as reproduced in the source material presents an apparent editorial anomaly: the entry mixes a definition of "equitable defense" with the beginning of the *definite* entry ("Bounded, limited, defined: determinate, precise, fixed"). Researchers consulting the original Anderson volume should verify that the full *definite* entry is intact and that no content has been displaced.

Historical Dictionary Support
Both Bouvier and Anderson offer functionally identical, brief definitions: *bounded, limited, defined; determinate, precise, fixed, certain* — in direct opposition to *indefinite*. This convergence reflects the term's character as a foundational descriptor rather than a technical term with its own legal apparatus. Neither source develops the concept beyond its adjectival function or discusses the enforceability consequences that dominate modern doctrine.
The absence of elaboration in both sources is itself informative. Nineteenth-century legal usage treated *definite* as transparent — a word carrying its common meaning directly into legal application. The development of *definiteness* as a formal doctrinal test (particularly in contract formation) is largely a twentieth-century refinement, arising from increased judicial attention to pre-contractual negotiations, preliminary agreements, and agreements to agree. Researchers relying on historical dictionaries alone will find adequate definitional support but no guidance on how courts operationalize the standard.
Webster's 1913 and the historical legal dictionaries are in agreement on core meaning, which confirms that the legal usage during that period tracked common usage closely.

Jurisdictional Note
The definiteness standard in contract law varies between common law jurisdictions and those that have adopted the UCC or analogous commercial codes. Article 2 of the UCC permits enforcement of contracts for the sale of goods even where one or more terms are left open, provided the parties intended to make a contract and a reasonably certain basis for remedy exists. This gap-filling approach materially differs from strict common law definiteness requirements still applied in many non-goods contract contexts.
