Definition
An adverb of pleading art, historically required as a technical term of indictment in piracy prosecutions. At common law and under early American practice, an indictment for piracy was fatally defective unless it charged that the defendant acted "piratically" — the word could not be replaced by synonyms, paraphrases, or circumlocutions, however accurate or descriptive. The term functioned as a term of art signaling the specific legal character of the offense, distinct from ordinary felony or robbery, and its omission went to the sufficiency of the charge itself.
Common Language
Modern common usage (Wiktionary): "In a piratical manner."
Historical common usage (Webster's 1913): Not independently defined; derived from "piratical," meaning of or pertaining to pirates or piracy.
The common-language meaning is merely descriptive — acting like a pirate. The legal meaning is narrower and more technical: it is a required word of art in a criminal pleading, not a general descriptor. A prosecutor who substituted "feloniously and in the manner of a pirate" for "piratically" did not satisfy the pleading requirement, even though the meaning was equivalent to a general reader. The legal significance is procedural and formal, not semantic.
Why It Matters in Research
This term appears almost exclusively in pleading manuals, criminal law treatises, and piracy indictments — not in substantive discussions of what piracy is. A researcher encountering "piratically" in a historical indictment or form book should understand immediately that its presence (or absence) was a threshold issue going to the validity of the charge, not merely a stylistic choice.
The term is a useful marker for identifying the common-law pleading tradition around piracy. Because piracy was tried in admiralty and under statutes (in the United States, principally under federal jurisdiction), indictment forms for piracy diverge from ordinary felony indictments. Historical sources treating piracy substantively — what acts constitute it, jurisdictional questions, the law of nations dimension — will often not mention "piratically" at all, since it belongs to the pleading layer, not the definitional layer. Researchers working across both layers should not expect the sources to overlap.
The Rapalje & Lawrence entry separately flags the compound phrase "PIRATICALLY AND FELONIOUSLY" as it appeared in statute, suggesting that some statutory drafting incorporated both terms in conjunction, which may affect how researchers read indictments charging under specific federal piracy statutes versus those charging under common-law piracy. This pairing is worth noting when comparing indictment forms across time periods.
Because strict pleading requirements of this kind were progressively relaxed under modern federal and state procedural codes — which generally require only a plain and concise statement of the offense — "piratically" as a mandatory term has no meaningful role in contemporary indictment practice. Its appearance in modern legal research is almost entirely historical.
Historical Dictionary Support
All four source dictionaries agree on the core proposition: "piratically" is a technical word of pleading that must appear in a piracy indictment and cannot be substituted. The authorities cited are consistent across the sources — Coke's Third Institute at page 112, Hawkins's Pleas of the Crown, and Chitty's Criminal Law — pointing to a settled common-law rule rather than a disputed or evolving one.
Bouvier's is the most complete entry, specifying that the word is "essential to charge the crime of piracy" and that it "cannot be supplied by another word or any circumlocution." This formulation is stricter than a mere preference: omission was a pleading defect, not a minor irregularity. Rapalje & Lawrence adds the statutory pairing ("piratically and feloniously") and cross-references American case authority, suggesting the requirement persisted into American practice and was not merely an English inheritance left behind at the founding.
What the historical dictionaries do not address: why this particular word carried such indispensable force — whether rooted in the admiralty origins of piracy jurisdiction, the law-of-nations character of the offense, or simply crystallized common-law pleading habit. Researchers seeking that explanation will need to go to the treatises cited (Hawkins, Coke, Chitty) rather than to the dictionary sources themselves.
Jurisdictional Note
The requirement appears rooted in English common law and was carried into early American federal practice. Because piracy is a federal matter in the United States under Article I of the Constitution, state indictment practice is not relevant here. Modern federal pleading rules have displaced strict technical word requirements, so the rule is effectively historical in American courts.
