Definition
To deprive, in legal usage, means to take away, withhold, or deny a person's recognized interest in life, liberty, or property. The term carries constitutional weight primarily through two provisions: the Due Process Clauses of the Fifth and Fourteenth Amendments, which prohibit government from depriving any person of life, liberty, or property without due process of law.
In constitutional property analysis, courts have treated "deprive" as functionally equivalent to "take" — signifying a direct appropriation, dispossession, or seizure that extinguishes or substantially strips the owner's interest. The word does not appear with a textual definition in the Constitution, and its meaning has been developed through judicial construction, keyed to historical usage and context.
In criminal law, "deprive" also appears in statutes governing theft and civil rights offenses, where it generally means to withhold property from the owner permanently or for an extended period, or to dispose of it in a manner that makes recovery unlikely.
Common Language
Modern common usage (Wiktionary): To take something away from someone and keep it away; to deny someone something; to bereave.
Historical common usage (Webster's 1913): To dispossess; to bereave; to divest; to hinder from possessing; to debar; to shut out from. Also, to divest of office; to depose.
The common meaning and the constitutional legal meaning overlap substantially but diverge at the edges. In ordinary speech, "deprive" can describe temporary denial or partial withholding. In constitutional due process analysis, courts have historically required something closer to a complete dispossession or direct appropriation before the term triggers procedural or substantive protection — a threshold that matters when governments argue that regulations merely limit use without rising to a constitutional deprivation.
Common Confusion
DEPRIVE vs. TAKE: In takings jurisprudence, "deprive" (Fifth/Fourteenth Amendment due process) and "take" (Fifth Amendment Takings Clause) are doctrinally distinct but historically treated as synonymous in many early sources. The historical dictionaries reflect this conflation: Black's, Bouvier's, and Anderson's all define "deprive" simply by equating it with "take" in the eminent domain context. Modern constitutional law has separated these tracks. A "taking" triggers the Takings Clause and requires compensation. A "deprivation" without due process triggers a due process claim and may require procedural protections, fair hearings, or substantive justification — not necessarily compensation. Researchers conflating these terms risk misreading both the doctrine and the remedy available.
DEPRIVE vs. INFRINGE: Some statutes and constitutional provisions use "infringe" (as in the Second Amendment) rather than "deprive." These are not interchangeable. Deprivation implies removal of an existing entitlement; infringement may capture partial or indirect burdens on a right.
Why It Matters in Research
The historical legal dictionaries define "deprive" almost entirely within the property-and-eminent-domain context, treating it as a synonym for "take." Researchers working in criminal law, civil rights, or liberty-based due process claims will find this coverage thin and potentially misleading. The constitutional application of "deprive" to life and liberty — not just property — expanded dramatically through Fourteenth Amendment doctrine, substantive due process, and section 1983 litigation, none of which is meaningfully addressed in these historical sources.
Key research traps:
1. Period sources (pre-1900) focus on property deprivation through eminent domain. If you are researching deprivation of liberty or procedural due process in early sources, expect near-silence or indirect treatment under "due process" rather than "deprive" as a standalone entry.
2. The criminal law meaning of "deprive" — found in modern theft statutes and federal civil rights statutes — is absent from all four historical dictionary entries. The Model Penal Code's definition (withholding property permanently or under circumstances that make restoration unlikely) represents a distinct usage that postdates these sources entirely.
3. In civil rights research, "deprivation" is a term of art in 42 U.S.C. § 1983 litigation. A § 1983 claim requires a deprivation of a federally protected right under color of state law. Early sources provide no guidance on this usage.
4. Jurisdictional variation in state due process clauses matters: some state constitutions track the federal language; others provide independent or broader protections. "Deprive" in a state constitutional provision may be construed differently than the federal analog.
5. Connect this term to the Lucas total deprivation rule in takings law: when government regulation deprives an owner of all economically beneficial use of property, it is treated as a categorical taking requiring compensation — a modern synthesis that sharpens the historical equation of "deprive" with "take" into a specific doctrinal trigger.
Historical Dictionary Support
All four historical sources converge on a single proposition: in constitutional property provisions, "deprive" means the same as "take" — a complete seizure, direct appropriation, or dispossession of the owner. Black's (both editions) and Bouvier's cite overlapping Pennsylvania authority (Sharpless v. Philadelphia) for this equivalence. Anderson's tracks Bouvier's closely.
Bouvier's and Anderson's add a notable methodological point: because the Constitution provides no textual definition of "deprive" as used in the Fourteenth Amendment, courts must look to historical usage to determine its meaning — a principle that remains relevant in contemporary originalist and textualist analysis.
What the historical sources miss: none addresses deprivation of liberty, deprivation in criminal statutes, or the procedural versus substantive dimensions of due process deprivation claims. The entries are useful as a baseline for the property context but should not be treated as comprehensive accounts of the term's legal reach.
Jurisdictional Note
Federal constitutional doctrine under the Fifth and Fourteenth Amendments governs the baseline meaning of "deprive" in due process and takings analysis, but state courts interpreting parallel provisions in state constitutions may apply different thresholds. Several states construe their own due process or property clauses to prohibit deprivations that fall short of a federal constitutional violation, particularly in regulatory contexts.
