Definition
In law, "symbol" operates across several distinct contexts rather than as a single unified legal concept.
1. Trade-marks. A symbol is any visible sign, device, or mark used to identify the source of goods or services and distinguish them from those of others. Trademark law protects symbols as commercial identifiers, extending coverage well beyond words to include shapes, colors, sounds, and images that acquire distinctiveness in the marketplace.
2. Symbolic delivery. In property and commercial law, a symbol is a physical object delivered in place of the actual subject matter of a transaction, standing as a token representing transfer of a larger or less movable thing. The classic example is a bill of lading delivered to represent merchandise in transit. The delivery of the symbol effects the legal transfer as though the goods themselves had passed hands.
3. Constitutional law (expressive conduct). In First Amendment analysis, a symbol is any object, image, or act that communicates a message, potentially qualifying as protected expressive conduct. Flag burning, armband wearing, and similar acts have been analyzed as symbolic speech, triggering constitutional scrutiny when the government seeks to regulate the communicative, rather than the purely physical, dimension of conduct.
Common Language
Modern common usage (Wiktionary): A character or glyph representing an idea, concept, or object; more broadly, anything considered the embodiment or cardinal exemplar of a concept or theme.
Historical common usage (Webster's 1913): A visible sign or representation of an idea; anything which suggests an idea or quality, or another thing, as by resemblance or by convention — an emblem, type, or figure.
The common meaning is not far from legal usage, but the gap matters in research. In ordinary speech, a symbol is primarily a representational or cultural concept. In law, the term does real functional work: a symbol can effect a property transfer (symbolic delivery), secure enforceable commercial rights (trade-marks), or determine whether government regulation survives constitutional scrutiny (expressive conduct). The legal question is not what the symbol means culturally, but what legal consequences attach to its use or delivery.
Recognized Forms
/SUBTYPES
Symbolic Delivery: The surrender of a representative object — a key, bill of lading, deed, warehouse receipt — in place of actual manual delivery of the thing transferred. Recognized in sale of goods, real property, and bailment law.
Trademark Symbol: A device, logo, word, or combination used in commerce to indicate source. Protected marks may be registered (carrying the ® designation) or unregistered (carrying TM or SM designations as common law claims).
Symbol as Expressive Conduct (Symbolic Speech): Nonverbal acts or displays that carry a sufficiently clear communicative message to qualify for First Amendment consideration. Whether protection attaches depends on whether the government's regulatory interest is unrelated to suppressing the message.
Why It Matters in Research
The fragmentation of this term across legal domains is the primary research hazard. A researcher using "symbol" as a search term in a historical corpus will retrieve cases and commentary from at least three distinct doctrinal areas — property, commercial law, and constitutional law — with no natural sorting mechanism. Each area uses the word to mean something structurally different.
For symbolic delivery: the doctrine predates modern commercial codes and appears extensively in 19th- and early 20th-century case law and equity decisions involving bills of lading, warehouse receipts, and conveyancing. The UCC later codified much of this practice under Articles 2 and 7 (documents of title), but the older vocabulary persists in historical sources. Researchers should not assume continuity of doctrine when the same terminology appears across pre- and post-UCC materials.
For trademark: Anderson's entry routes the reader directly to the TRADE-MARK entry, signaling that "symbol" is a subordinate term in trademark analysis rather than a standalone concept in that era. Modern trademark doctrine has significantly expanded — trade dress, color, and non-traditional marks were largely unrecognized in Anderson's time — so historical dictionary treatment will understate current scope.
For constitutional law: the symbolic speech doctrine is almost entirely a post-1960s development. No 19th-century or early 20th-century legal dictionary will address it. Researchers working in First Amendment and expressive conduct must look to case law and constitutional commentary rather than historical general dictionaries.
Cross-corpus alert: entries for DELIVERY, TRADE-MARK, BILL OF LADING, and EXPRESSIVE CONDUCT will each illuminate a dimension of SYMBOL that the symbol entry itself does not fully develop. Treat this entry as an index node rather than a terminal reference.
Historical Dictionary Support
Anderson's Dictionary of Law is the sole historical source in the current corpus, and its treatment is instructive precisely because of its brevity. The entry dispatches trademark usage by cross-reference to TRADE-MARK, and addresses symbolic delivery with a single clean example — bill of lading as symbol for merchandise — directing the researcher to DELIVERY and SALE. This spare treatment reflects how "symbol" functioned in late 19th-century American legal writing: not a primary term of art but a descriptor for the mechanism by which representative objects stood in for actual property in transactions.
Anderson's gives no constitutional dimension whatsoever, which is accurate for his era. The symbolic speech doctrine did not exist as a recognized body of law when Anderson wrote. The absence is not a deficiency in the dictionary; it is a reliable signal that any researcher finding "symbol" in constitutional context in pre-20th-century sources is looking at a different usage — likely theological or rhetorical rather than doctrinal.
Webster's 1913 definition aligns with Anderson's implicit understanding: a symbol is a representational device, one thing standing for another. The legal innovation layered on top of that common meaning is the consequence: legal effect can attach to the delivery or use of the representative object itself.
Jurisdictional Note
Symbolic delivery doctrine and its interaction with documentary title is substantially uniform under the UCC in American jurisdictions, but pre-UCC state law varied. Trademark registration and protection involves both federal law (Lanham Act) and residual state common law. Symbolic speech doctrine is a federal constitutional floor; state constitutions may provide broader expressive conduct protections.
