Definition
Zetetick is an archaic legal and philosophical term meaning proceeding by inquiry — that is, advancing toward a conclusion through investigation and questioning rather than by assertion or assumption. The term describes a method of reasoning characterized by systematic inquiry, examination, and the suspension of judgment pending investigation.
In legal and scholarly usage, the term carries no technical procedural weight of its own. It appears in the historical dictionaries as a descriptor of reasoning method rather than as a term of art with operative legal consequences.

Common Language
Modern common usage (Wiktionary): Archaic form of "zetetic" — of or relating to inquiry; proceeding by investigation.
Historical common usage (Webster's 1913): Not separately defined; "zetetic" appears as an adjective meaning "seeking" or "proceeding by inquiry," derived from the Greek zetetikos, and applied to a method of reasoning associated with the ancient skeptical philosophical tradition.
The gap between common and legal usage here is narrow but worth noting: in philosophical tradition, "zetetic" carries a specific association with Pyrrhonian skepticism — the indefinite suspension of judgment as a permanent posture. In the legal dictionaries, this skeptical connotation is shed entirely; the term is reduced to a neutral description of inquiry-based procedure, with no implication of suspended judgment or philosophical doubt.

Why It Matters in Research
Researchers encountering "zetetick" in historical legal sources should treat it as a methodological descriptor rather than a term of art with discrete legal consequences. It will not appear in case reporters or statutes as a operative term. Its appearances are essentially bibliographic: Black's in both the 1st and 2nd editions records it on the authority of the Encyclopaedia Londinensis, signaling that the entry was drawn from an encyclopedic rather than a purely legal source.
The placement of ZETETICK in Black's immediately before ZIGARI (or ZINGARI) in both editions reflects simple alphabetical ordering, not conceptual connection. Researchers scanning microfilm or digitized versions of early Black's editions should be aware that these two entries are proximate and entirely unrelated.
The term is unlikely to be a productive search term in case law databases. Its value is almost entirely confined to understanding the vocabulary of historical legal scholarship and the range of sources Black drew upon in compiling the early editions of his dictionary.
Because the term derives its authority in the legal dictionaries from the Encyclopaedia Londinensis rather than from case law, statute, or treatise, it carries no doctrinal weight and should not be cited as legal authority.

Historical Dictionary Support
Both the 1st and 2nd editions of Black's Law Dictionary give identical definitions: "Proceeding by inquiry," with a citation to the Encyclopaedia Londinensis (abbreviated "Enc. Lond."). This consistency across editions indicates that the 2nd edition made no independent investigation of the term and simply carried the entry forward.
The Encyclopaedia Londinensis was an early nineteenth-century British general encyclopedia, not a legal authority. Its appearance as the sole source for this entry places ZETETICK among a small category of Black's entries that reflect the compiler's broad encyclopedic sourcing practices rather than the distillation of legal doctrine.
Neither edition expands on the term, provides illustrative usage, or connects it to any legal proceeding, principle, or rule. The definition stands essentially as a glossary notation — one word translated to a brief phrase — with no further elaboration. Historical dictionaries beyond Black's do not appear to have independently adopted or developed the term as a legal concept.
