Definition
Intent is the mental state in which a person consciously purposes a result or is substantially certain that a result will follow from their act. It is the mind directed toward a specific object or outcome — not merely the act itself, but the accompanying resolve that gives the act its legal character.
Intent operates across multiple areas of law and carries distinct meanings depending on context:
1. Criminal intent. The deliberate purpose to commit a prohibited act or bring about a prohibited result. Criminal intent is generally required for conviction of common-law crimes and many statutory offenses, distinguishing willful wrongdoing from accident or negligence. Specific intent requires that the actor not only commit the act but have a further purpose beyond it (e.g., intent to permanently deprive in theft). General intent requires only that the actor meant to do the act, not necessarily its precise consequence.
2. Tortious intent. In tort law, intent means either (a) a desire to bring about the consequence, or (b) a belief that the consequence is substantially certain to result. Mere foreseeability of harm is not intent — that is the domain of negligence. This distinction is foundational to the line between intentional torts and negligence.
3. Legislative intent. The purpose or meaning that a legislative body sought to express through enacted law. Courts consult legislative history, committee reports, and the statutory text itself to determine legislative intent when a statute is ambiguous. This use of the word is interpretive rather than behavioral.
4. Testamentary intent. The genuine purpose of a testator to direct the disposition of their property by a particular instrument. Courts will not give effect to a document as a will unless testamentary intent is established.

Common Language
Modern common usage (Wiktionary): Something that is intended; the state of someone's mind at the time of committing an offence.
Historical common usage (Webster's 1913): Having the mind closely directed to or bent on an object; sedulous; eager in pursuit of an object.
The ordinary word "intent" suggests a person's general aim or purpose — what they were "going for." The legal meaning is more precise and more demanding. Law distinguishes between wanting a result (desire) and knowing a result will occur (substantial certainty), and it treats both as intent. A person who fires into a crowd, indifferent to who is hit, may have no desire to hit any particular victim — but the law treats the outcome as intended. Researchers reading historical sources should note that the common understanding of intent as purpose or aim is only half the legal picture.

Common Confusion
Intent is frequently conflated with motive, knowledge, and recklessness — four distinct mental states that law treats separately.
Motive is the reason a person acted; intent is the purpose directing the act itself. A person may have good motives and still commit an intentional tort or crime.
Knowledge, in the Model Penal Code framework and in many tort contexts, describes awareness of a circumstance or practical certainty about a result — closely related to intent but formally separate. Some jurisdictions treat knowledge and intent as synonymous for certain offenses; others do not.
Recklessness involves conscious disregard of a substantial and unjustifiable risk. It is not intent. A reckless actor may not want the harmful result and may not believe it is substantially certain to occur — they simply ignore the risk. The gap between recklessness and intent has major consequences for which tort claims are available, whether punitive damages apply, and which criminal charge fits the conduct.

Core Elements
Because intent is a mental state, its proof and legal structure follow a recognized framework across criminal and tort law:
1. Subjective component. Intent exists in the mind of the actor. The factfinder must infer it from external evidence — words, conduct, surrounding circumstances — because direct proof is rarely available.
2. Purpose or substantial certainty. The actor either (a) consciously desires the result, or (b) knows with substantial certainty that the result will follow. Both satisfy the legal threshold for intent.
3. Concurrence with the act. Intent must exist at the time of the act. Post-hoc rationalization or later formed purpose does not supply intent retroactively. In criminal law, this is the concurrence principle.
4. Transferability. In tort law (and in some criminal contexts), intent can transfer from the intended target to an unintended victim, or across certain intentional tort categories. This is the transferred intent doctrine. The actor's intent to harm one person satisfies the intent element even when a different person is harmed.

Why It Matters in Research
Intent is one of the most researched and most contested mental-state terms in the Law Mind corpus. Several navigational points are essential:
Historical sources conflate specific and general intent. Black's 1st and 2nd editions treat intent largely as a unified concept — "purpose; formulated design; a resolve." Modern criminal law has disaggregated this into specific intent, general intent, and in Model Penal Code jurisdictions, purpose, knowledge, recklessness, and negligence. Research in older materials will not map cleanly onto this taxonomy.
The Model Penal Code divide matters enormously. Roughly half of American jurisdictions have adopted MPC-influenced mental-state language that largely replaces "intent" with "purpose" and "knowledge" as separate categories. In those jurisdictions, looking for "intent" in statutes may miss the operative term. Researchers working with state criminal codes after 1962 should check whether the jurisdiction follows MPC terminology.
Tortious intent and criminal intent are not synonymous. A finding of intent for tort purposes (including the substantial certainty standard) does not automatically establish criminal intent, and vice versa. Sources that use intent without specifying the legal context should be read with this distinction in mind.
Legislative intent is a distinct research track. Primary sources for legislative intent (committee reports, floor debates, prior drafts) are separate from the case law developing behavioral intent. Conflating these in a research query will produce noise across both tracks.
Transferred intent appears in the encyclopedia entries linked above. Researchers exploring whether intent satisfies the elements of battery, assault, false imprisonment, trespass to chattels, or trespass to land should consult the transferred intent materials, which address how intent moves across tort categories.

Historical Dictionary Support
Black's 1st and 2nd editions are in close agreement, defining intent as "purpose; formulated design; a resolve to do or forbear a particular act; aim; determination" and noting its literal sense as "the stretching of the mind or will towards a particular object." Both emphasize that intent accompanies the outward act and reflects mental action at its most advanced point. The definition is behavioral and unified — there is no internal distinction between desire and substantial certainty.
Burrill similarly roots the term in determination to act and design, drawing on the Latin intendere (to stretch toward). His framing reinforces the purposive model that dominated pre-MPC legal thinking.
Bouvier redirects to related compound entries — COMMON INTENT, CRIMINAL INTENT, LEGISLATIVE INTENT — a structurally significant choice. It signals that Bouvier treated intent as a framework term requiring qualification, not a self-standing concept. Researchers using Bouvier should follow those cross-references; the standalone entry offers little.
Anderson's entry for intent appears to have been corrupted in the source material and reflects content from a different headword. It should be disregarded.
What the historical dictionaries collectively miss: the substantial certainty prong of modern intent, the MPC's dissolution of "intent" as a unified category, and the formal transferred intent doctrine as developed in twentieth-century tort law. These are not gaps in their era — they are developments that postdate the dictionaries and must be layered in from modern sources.

Jurisdictional Note
In MPC-influenced jurisdictions, statutory criminal law largely replaces "intent" with "purposely" and "knowingly" as distinct mental states. Jurisdictions retaining traditional common-law language continue to use specific and general intent frameworks, producing different outcomes on the same facts. Researchers working across state criminal law should treat "intent" as a jurisdiction-specific term and verify the operative mental-state vocabulary before applying doctrine from one state to another.
