Definition
A communication directed to the public or to identifiable individuals, designed to attract attention to a product, service, opportunity, or legal event. Legal usage encompasses two distinct contexts:
1. Commercial advertisement. A public notice promoting a commodity, service, or business — including print, broadcast, digital, and physical signage. In commercial law and consumer protection, the content and form of advertisements may give rise to legal obligations, including contract offers (in limited circumstances), warranty claims, and liability for deceptive or false statements.
2. Official or legal advertisement. A notice published in compliance with statutory or court-ordered requirements — such as publication of probate proceedings, partnership dissolutions, foreclosure sales, sheriff's sales, or summons by publication. Official advertisements carry legal effect independent of commercial intent; they substitute for or supplement direct notice to affected parties.

Common Language
Modern common usage (Wiktionary): A commercial solicitation designed to sell a commodity, service, or similar; also a public notice or recommendation of a product or service.
Historical common usage (Webster's 1913): "A public notice, especially a paid notice in some public print; anything that advertises." Earlier senses included simple notification or warning, now archaic.
The gap between common and legal meaning is most pronounced in the official advertisement context. Ordinary speakers understand an advertisement as inherently commercial and voluntary. In law, an advertisement may be a mandatory, court-or-statute-compelled publication with jurisdictional and procedural consequences — closer in function to formal notice than to marketing. A researcher who treats "advertisement" as synonymous with commercial promotion will miss a significant body of procedural law governing publication requirements.

Recognized Forms
/SUBTYPES
Official advertisement. A publication required by law or court order — notice of probate, insolvency, dissolution of partnership, tax sale, or judicial proceeding. Such publication constitutes constructive notice to the world and satisfies due process notice requirements where direct notice is impracticable.
Commercial advertisement. A voluntary public communication promoting a business interest. Subject to consumer protection statutes, FTC regulations, Lanham Act section 43(a) false advertising claims, and sector-specific regimes (FDA, SEC, FCC).
Offer by advertisement. A public promise, such as a reward offer, communicated through an advertisement. Courts have recognized that certain advertisements — particularly reward offers — constitute binding unilateral contract offers, accepted by performance. This remains a live doctrinal issue distinct from the general rule that advertisements are mere invitations to deal.

Why It Matters in Research
**The commercial/official divide is a persistent trap.** Historical sources — especially Anderson and Rapalje & Lawrence — give roughly equal weight to commercial and official advertisement contexts. Modern practitioners and researchers anchored in consumer protection or advertising law may overlook the official advertisement body of law entirely, and vice versa. Confirm which meaning controls in the source you are reading.
**Offer-by-advertisement doctrine requires careful dating.** The question of when an advertisement constitutes a binding offer rather than a mere invitation to deal has a long common law history. Historical dictionary sources frame this primarily through the reward-offer scenario. Modern cases extend (and sometimes contract) this doctrine. Do not assume historical and modern treatments are aligned.
**Regulatory overlay is entirely absent from historical sources.** Black's, Rapalje & Lawrence, and Anderson pre-date the Federal Trade Commission Act (1914), the Lanham Act (1946), and all FDA advertising restrictions. Historical definitions are descriptive of the common law landscape only. For any research touching deceptive advertising, comparative advertising, or pharmaceutical or securities marketing, the historical dictionaries are background only — the operative law is entirely statutory and regulatory.
**Publication sufficiency varies by jurisdiction and statute.** For official advertisements, what constitutes adequate publication — which newspaper, how many insertions, the required interval — is set by individual state statutes. The historical sources treat publication as constructive notice without specifying these requirements, which differ materially across jurisdictions and have changed over time.
**Digital and electronic advertising** is entirely outside the contemplation of any source dictionary here. Researchers applying historical definitions to online, social media, or programmatic advertising contexts must bridge a significant gap.

Historical Dictionary Support
The historical sources agree on the core definition: an advertisement is a notice communicated to the public or to individuals by means of print, handbill, or signage, designed to attract attention. Black's (both editions) lead with the public attention framing. Rapalje & Lawrence traces the Latin root (*advertere*, to turn to) and emphasizes the informational function — giving knowledge to individuals or the public. Anderson is the most practically useful of the three, distinguishing between general commercial advertisements and "official advertisement" as a term of art, and noting that newspaper publication under legal direction is equivalent to notice for procedural purposes.
Where the sources diverge slightly: Rapalje & Lawrence gives the most developed treatment of the reward-by-advertisement scenario, noting that an advertised reward operates as a unilateral offer — binding on the advertiser as to persons who respond, even if not yet binding as against those who have had no previous dealing with the offeror. Anderson cross-references publication doctrine more systematically. Black's (2nd ed.) is the most case-grounded, citing *Montford v. Allen*, *Haffner v. Barnard*, and *Commonwealth v. Johnson* for the proposition that a sign-board constitutes an advertisement within lottery statutes — a now-dated application, but useful for understanding the breadth of the term as historically construed.
What the historical sources miss: any treatment of advertising as a regulated commercial activity, consumer protection dimensions, false or deceptive advertising as a cause of action, or the constitutional (First Amendment) status of commercial speech. These are twentieth-century developments with no foothold in the dictionary literature here surveyed.

Jurisdictional Note
Official advertisement requirements — governing which publications qualify, required insertion frequency, and notice-triggering effect — are set by state statute and vary considerably. Federal regulatory advertising law (FTC, FDA, SEC, FCC) operates independently of state common law definitions and controls most commercial advertising contexts regardless of how state law defines the term.
