Definition
Capable of being accomplished or performed given the available means, circumstances, and resources. When a legal instrument, statute, or court order requires something to be done "as practicable" or "where practicable," the term sets a standard of reasonable feasibility rather than absolute possibility. It asks whether a thing can be done under real-world conditions — not merely whether it is theoretically conceivable.
The distinction from "possible" is foundational. Something may be possible in the abstract yet impracticable under the actual conditions at hand. Courts and drafters use "practicable" to build flexibility into legal obligations: the duty exists, but its performance is calibrated to what can reasonably be achieved given constraints of time, cost, physical circumstances, or available means.
The term appears most frequently in:
(1) Statutes and regulations imposing duties qualified by "as soon as practicable" or "to the extent practicable," which create enforceable but circumstance-sensitive obligations;
(2) Contract provisions specifying performance at the nearest or earliest practicable point, time, or place;
(3) Constitutional and procedural rules requiring notice, opportunity to be heard, or compliance "where practicable."

Common Language
Modern common usage (Wiktionary): Capable of being accomplished; feasible. Also: serving a useful function; available for use.
Historical common usage (Webster's 1913): That which may be practiced or performed; capable of being done or accomplished with available means or resources; feasible. Also: capable of being used or passed, as in a practicable road or weapon.
The common and legal meanings are closely aligned, but legal usage sharpens the distinction between "practicable" and "possible" in ways ordinary speech does not. In everyday language, the two words are often interchangeable. In legal instruments, the choice of "practicable" over "possible" is deliberate and carries interpretive weight: it signals that the obligation is bounded by realistic conditions, not absolute capacity.

Common Confusion
PRACTICABLE vs. POSSIBLE: These terms are frequently treated as synonyms in ordinary usage but diverge materially in legal construction. "Possible" asks whether something can exist or occur under any circumstances. "Practicable" asks whether it can be accomplished under the actual circumstances present. Anderson's entry captures this directly: an agreement to locate a railway station at the "nearest practicable point" was construed to mean the nearest point at which a depot could functionally be placed — not the geometrically nearest point, which might be impossible to build upon. Courts interpreting statutory or contractual language will look closely at which word the drafter chose.
PRACTICABLE vs. PRACTICAL: A separate and common slip. "Practical" relates to what is sensible, useful, or likely to work as a matter of judgment or experience. "Practicable" relates specifically to feasibility — whether execution is possible under available conditions. A plan may be practical (sensible) but not practicable (not feasible given current resources), or practicable but not practical (technically doable but unwise).

Why It Matters in Research
The word "practicable" functions as a legal qualifier that modifies the strictness of an obligation. Researchers examining statutory duties, regulatory compliance standards, or contract performance obligations must identify whether a "practicable" qualifier is present — and if so, who bears the burden of showing that compliance was or was not practicable.
In administrative law, "to the extent practicable" and "as soon as practicable" appear constantly in agency rulemaking, environmental compliance schedules, and public notice requirements. These phrases have been the subject of significant litigation over whether agencies satisfied their statutory obligations or whether regulated parties had adequate justification for delayed or partial compliance. The standard is not merely subjective inconvenience; courts have generally required a showing of genuine constraint.
In historical sources, the distinction between "practicable" and "possible" may not be drawn as precisely as modern usage demands. Researchers reading nineteenth-century contracts, pleadings, or statutes should not assume that "practicable" was always used with modern precision. Anderson's entry, for example, briefly defines the term in the context of a railway contract dispute, suggesting the courts of that era were actively working out the boundary between the two words. The interpretive history of a specific instrument may matter.
Jurisdictional treatment of "as soon as practicable" in notice statutes — particularly in insurance, probate, and civil procedure contexts — varies enough that researchers should not extrapolate from one jurisdiction's case law to another without verification.

Historical Dictionary Support
Anderson's Dictionary of Law addresses "practicable" economically but usefully. The entry appears under the broader heading PRÆSUMERE and pivots quickly to a practical illustration: a contract requiring a railway station to be placed at the "nearest practicable point" within a mile of a courthouse was held to mean not the nearest possible point, but the nearest point at which the depot could actually be constructed and used. This is the clearest expression in historical legal dictionary literature of the practicable/possible distinction as applied by courts.
Anderson does not offer a formal multi-part definition or enumerate elements, which reflects the term's treatment as a modifier rather than as a term of art with independent doctrinal content. What the historical dictionaries collectively reveal is that "practicable" has always operated contextually — its meaning derives from the obligation it qualifies, not from a freestanding definition.
Webster's 1913 adds the physical sense (a practicable road, a practicable breach in a military fortification) that confirms the core meaning: capable of being used or traversed under actual conditions, not merely in theory. This physical usage reinforces the legal interpretive approach.

Jurisdictional Note
The phrase "as soon as practicable" appears in statutes across all U.S. jurisdictions, but courts differ on how much flexibility it extends to regulated parties or agencies. Some courts treat it as near-equivalent to "promptly" or "without unreasonable delay"; others allow more latitude based on demonstrated constraints. International commercial contracts using "practicable" may encounter different interpretive conventions under English law, where the term has a similarly settled but independently developed construction.
