Definition
"Phy" as it appears in Burrill's Law Dictionary is an abbreviated form of "petition" as used in equity practice — specifically, a written application to a court of equity (chancery) setting out the circumstances upon which relief is sought. The abbreviation surfaces in Burrill's treatment of equity procedure, where it flags the Latin formula *peto* (I petition, I seek) found in Glanville and similar early sources. As a standalone headword, "phy" is not a term of art with independent legal meaning; it is a scribal or typographical artifact of the dictionary's condensed reference format, pointing the reader toward the substantive entry on equity petitions.
Common Language
Modern common usage (Wiktionary): A surname. No general vocabulary meaning in modern English.
Historical common usage (Latin): An interjection — roughly "pish!" or "tush!" — expressing dismissal or contempt (Terence, *Adelphoe* 3.3.58; noted in Priscian).
The gap here is complete rather than subtle: the Latin interjection and the modern surname share no connection to the equity procedure sense. A researcher encountering "phy" in a chancery document or legal index should not read it as an expression or a proper name. Its appearance in legal manuscript or dictionary contexts almost certainly signals the abbreviation for *petition* or the Latin root *peto*.
Why It Matters in Research
Researchers working in equity practice materials — particularly pre-codification chancery records, abridgments, and form books — will encounter compressed abbreviations constantly. "Phy" as an index entry or marginal notation is most reliably read as shorthand pointing toward petition practice rather than as a discrete legal concept. The Burrill entry itself is a condensed cross-reference: it quotes Glanville's formula (*Peto versus talem tantum terræ cum pertinentiis, in tali villa*) to illustrate the form of a petitioner's demand, connecting the abbreviation to the deep common law tradition of the original writ petitioning for land.
The practical trap: researchers using full-text search across historical legal corpora may retrieve "phy" as noise — surnames, Latin interjections, or typographical fragments — rather than substantive legal usage. When "phy" appears in proximity to chancery or equity materials, cross-reference against petition entries, bill-and-answer procedure, and motion practice before concluding that the term has independent significance.
Burrill's entry also connects to a broader research thread: the equity petition was the functional alternative to the common law writ in circumstances where a fuller narrative statement was required. Barbour's *Chancery Practice* (cited by Burrill) is the relevant period treatise for understanding when petition procedure was required versus a simple notice of motion.
Historical Dictionary Support
Burrill's Law Dictionary is the sole source dictionary here, and it treats "phy" not as a freestanding term but as an abbreviated gateway to equity petition practice. The entry quotes Glanville (*lib. 2, c. 3*) for the form of the petitory demand in land actions and cites Barbour's *Chancery Practice* for the modern equity rule requiring a petition when the application requires fuller statement than a notice of motion allows.
No other major historical legal dictionaries — not Black's, not Bouvier's, not Tomlin's — carry a headword entry for "phy." This strongly suggests that Burrill's treatment is idiosyncratic to his indexing method rather than evidence of "phy" as a recognized term of art in any jurisdiction or period. Researchers should treat Burrill's entry as a navigational pointer, not as authority for the term itself.
Jurisdictional Note
Equity petition practice varied between English chancery and American state equity courts, and was substantially transformed or abolished in jurisdictions that merged law and equity under the Field Code (New York, 1848) and later the Federal Rules of Civil Procedure (1938). Historical sources using "phy" or similar abbreviations should be read against the procedural regime in force at the time and place of the document.
