Definition
A Latin adjective from Roman law meaning clear, evident, or manifest — used to describe something so plainly apparent that it requires no further demonstration or proof. In legal contexts, *manifestus* most commonly appears as a doctrinal modifier: a fact, act, or condition described as *manifestus* is treated as self-evident and removed from ordinary evidentiary requirements. The term is the root of the maxim *manifesta probatione non indigent* (manifest things need no proof), which expresses one of the foundational presumptions of legal reasoning across common law and civil law traditions.

Common Language
Modern common usage (Wiktionary): "Manifest" — clearly apparent to the sight or understanding; obvious.
Historical common usage (Webster's 1913): "Manifest" — clearly visible to the eye or obvious to the understanding; not obscure or hidden; apparent; plain; evident; conspicuous.
The common and legal meanings track closely here, but the legal deployment of *manifestus* carries a procedural consequence the ordinary meaning lacks: in law, designating something as *manifestus* is not merely descriptive but operative. It triggers a doctrine — that the thing so described needs no proof — which can determine the outcome of evidentiary disputes. The everyday word describes a quality; the legal term invokes a rule.

Why It Matters in Research
Researchers encounter *manifestus* almost exclusively in two contexts: Latin maxims embedded in early English common law reports and treatises, and civil law materials derived from Roman sources. The term rarely appears as a standalone term of art in modern legal writing; instead, it survives through its derivative maxim and through English-language descendants like "manifest error," "manifest weight of the evidence," and "manifest disregard of the law" — none of which should be read as direct translations of *manifestus* without attention to how those modern phrases have acquired independent doctrinal content.
The maxim *manifesta probatione non indigent* appears in Coke's Reports and similar early sources. Researchers should treat these citations with care: the maxim functions as a rhetorical and logical principle in those materials, not as a codified evidentiary rule with modern procedural mechanics. Transplanting the maxim's logic directly into contemporary evidentiary analysis risks misreading its scope.
In civil law research — particularly materials dealing with Roman law, Louisiana law, or comparative private law — *manifestus* may appear in discussions of *furtum manifestum* (manifest theft), a category of Roman law in which a thief caught in the act was subject to harsher penalties than one prosecuted later. This usage is historically significant and distinct from the evidential sense: here *manifestus* describes the mode of detection, not merely the clarity of proof. Researchers moving between Roman law sources and common law materials should flag this distinction to avoid conflating two different legal applications of the same Latin term.
The corpus connection to run: any Law Mind source using "manifest" as a legal term of art (manifest error, manifest injustice, manifest disregard) should be checked against this entry and the *furtum manifestum* background to determine whether the author is invoking the Roman evidential tradition, the common law maxim tradition, or a modern doctrinal standard with independent development.

Historical Dictionary Support
Burrill's entry is concise and accurate as far as it goes, glossing *manifestus* as "clear; evident; manifest" and anchoring the evidential maxim to Coke's Reports (*7 Co. 40b, Bedell's Case*). This is the standard treatment for a Latin term whose legal significance is primarily transmitted through a single well-known maxim rather than through an independent doctrinal life.
What Burrill does not address is the Roman law background of *furtum manifestum*, which is the term's most consequential technical application in pre-modern jurisprudence. Researchers relying solely on Burrill's gloss will have an adequate account of the maxim but an incomplete picture of how *manifestus* functioned in the civil law tradition from which it originated. Later civil law dictionaries and treatises on Roman private law fill this gap.
No historical legal dictionary in common circulation gives *manifestus* a full independent entry with developed analysis. It is consistently treated as a particle in compound terms and maxims rather than as a freestanding concept — which is an accurate reflection of how the word actually operates in legal Latin.
