Definition
In historical English law, TAN referred to a list or register of property assessed or rated for the purpose of taxation. The term appears in early legal and fiscal administration as a documentary instrument — a roll or schedule identifying taxable goods or landholdings and the valuations placed upon them for the levy of a tax.
The term is narrow, archaic, and almost entirely confined to historical sources. It carries no continuing operative meaning in modern Anglo-American law.
Common Language
Modern common usage (Wiktionary): A Chinese surname of Hokkien origin. Also used in general English as a noun or adjective describing a light brown color, or as a verb meaning to expose skin to the sun.
Historical common usage (Webster's 1913): Webster's 1913 redirects to "Picul," a unit of weight used in East and Southeast Asian trade, suggesting the dictionary treated "tan" in that context as a unit of measure in Asian commerce rather than as an English word with independent significance.
The gap between the common and legal meanings here is total. The legal term TAN is an early administrative or fiscal term from English legal history with no relationship to color, surnames, or units of weight. A researcher encountering "tan" in a historical English legal document should not assume any common English meaning applies.
Why It Matters in Research
Researchers are most likely to encounter TAN in pre-modern English fiscal and administrative records — subsidy rolls, tax assessments, manorial documents, or glossaries of early English legal instruments. Because the term is rare and largely displaced by later vocabulary, it will not appear in most standard modern legal dictionaries, and its absence from those sources can mislead a researcher into assuming the word is used colloquially or is a copying error.
The principal trap is misidentification: a researcher unfamiliar with the term may read it as a common English word (a color, a verb), a personal name, or a scribal abbreviation for another term. Burrill's gloss — "list of property rated for paying tax" — aligns TAN with instruments like subsidy rolls and assessment schedules, which are well-represented in English historical archives.
Researchers working in English legal history who encounter TAN should cross-reference it against fiscal terminology from the same period: TALLAGE, SCUTAGE, SUBSIDY, and RATE, all of which describe related but distinct mechanisms of taxation or assessment. The document type itself — a rated list — is closely related to what later practice would call a rate book or assessment roll.
Because this term derives from Spelman's glossarial tradition (Burrill cites Spelman as his authority), researchers should note that Spelman's Glossarium Archaiologicum is the upstream source and may contain a fuller treatment. Terms that appear in Burrill via Spelman are often drawn from medieval Latin or Anglo-Norman administrative practice and may have Latin equivalents that appear more frequently in the primary sources than the English form does.
Historical Dictionary Support
Burrill's Law Dictionary provides the sole historical dictionary entry identified for TAN in its legal sense. Burrill's definition is terse: "list of property rated for paying tax," attributed to Spelman. This is consistent with Spelman's broader project of recovering and defining obsolete terms from English legal and administrative history, particularly those appearing in subsidy records and fiscal instruments.
No other major historical legal dictionaries in the Law Mind corpus — not Bouvier, not Black's early editions — carry an independent entry for TAN in this sense. This silence is itself informative: the term was obscure even by the nineteenth century and was not part of the working vocabulary of practicing lawyers. Its preservation in Burrill reflects the antiquarian and historical dimension of that dictionary rather than any continuing practical relevance.
Wharton's Law Lexicon and Jacob's Law Dictionary, which also draw on English legal history, do not appear to carry the term, further confirming its marginal status.
Jurisdictional Note
TAN in its legal sense is exclusively English in origin and has no recognized counterpart in American, Scottish, or Irish legal traditions. Researchers working outside English historical legal materials will not encounter it.
