Definition
"Con" appears in legal materials primarily as a Latin prefix and abbreviation, not as a standalone legal term. It carries two principal functions: 1. As a prefix: A contracted form of the Latin cum (meaning "with" or "together"), appearing in compound legal words and phrases—such as consideration, conspiracy, contract, conveyance, and many others. In this use, "con-" signals joint action, combination, or association. 2. As an abbreviation: Shortened form of contra ("against") or, less frequently, of conversation (as in criminal conversation). In older case reports, legal memoranda, and headnotes, "con" appears beside an argument, authority, or judicial opinion to indicate opposition—as in "pro and con" analysis.
Common Language
Modern common usage (Wiktionary): "Con" in everyday English is used as a diminutive given name (Conor, Cornelius), an abbreviation for Conservative, or colloquially as a noun or verb meaning fraud, swindle, or to deceive (as in "con artist"). Historical common usage (Webster's 1913): "Against the affirmative side; in opposition; on the negative side—the antithesis of pro, and usually in connection with it." The Webster's 1913 usage—opposition to a proposition—is the one that most closely tracks legal usage, where "con" signals an argument against, an authority in opposition, or a dissenting position. The modern colloquial meaning (fraud, deception) has no direct legal technical counterpart under this headword, though it appears in informal shorthand for confidence scheme or confidence fraud.
Common Confusion
"Con" as abbreviation for contra is sometimes confused with "con" as prefix (cum). These are functionally unrelated. When a researcher encounters "con." in an older legal text, the period signals abbreviation (most likely contra or conversation); when "con" is attached directly to a root word with no punctuation break, it is the Latin prefix. Researchers should also distinguish "con" from "cum," which appears in full in many Latin maxims and case titles. The two are etymologically related but contextually distinct—"cum" most often appears in full phrases (as in "cum testamento annexo"), while "con" as prefix is absorbed into English legal vocabulary.
Why It Matters in Research
For corpus researchers, "con" functions as a stealth term: its meaning is entirely dependent on context, and it shifts between prefix, abbreviation, and informal shorthand across centuries of legal writing. In older reports and digests—particularly English common law reporters and early American case collections—"con." with a period typically abbreviates contra, flagging a contrary authority or dissenting judge. Bouvier and Anderson both confirm this abbreviation use. Researchers scanning pre-1900 legal indices or headnotes should not overlook these notations; they often signal the existence of a conflicting line of authority that modern citators may not surface. As a prefix, "con-" permeates legal vocabulary so thoroughly that it is invisible to most researchers. Understanding that con- signals joint or combined action helps decode unfamiliar compound terms—particularly in feudal law, canon law, and early civil procedure, where Latinized compound terms were standard. The abbreviation for conversation (i.e., criminal conversation, a now-largely-abolished tort) also appears as "con." in older English reports and pleading records. Researchers working in eighteenth- and nineteenth-century family law or tort materials should be alert to this usage. No significant jurisdictional drift attaches to "con" itself, though the underlying terms it abbreviates or prefixes may carry jurisdiction-specific meanings.
Historical Dictionary Support
Anderson's Dictionary of Law provides the most direct treatment, identifying both functions: "con" as a form of cum in compound words and as an abbreviation of contra and of conversation. This is consistent with general usage across historical legal sources. Bouvier's material, as retrieved, does not address "con" directly; the excerpt concerns statutory construction doctrine and appears to be a retrieval artifact from an adjacent entry. Burrill's material similarly does not treat "con" as a standalone entry; the excerpted text concerns compurgators (consacramentales, conjuratores) and feudal procedure—terms that carry the con- prefix but are discussed under separate headwords. The historical dictionaries collectively confirm that "con" was treated as a grammatical and abbreviatory element rather than a substantive legal term in its own right. No historical source assigns independent legal effect to the bare term.

STRUCTION, DOCTRINE OF. A rule of statute interpretation whereby the court shall look with disfavor upon a change whereby parties who have contracted with the government on the faith of a former construction might be injured; especially when it is attempted to make the change retroactive, and to require from a contractor a return of moneys paid to him under the former construction. 194 U. S. 99; 142 U. S. 621. But it is well settled that it is only where the language of the statute is ambigu- ous and susceptible of two reasonable inter- pretations that weight is given to the doctrine of contemporaneous construction. Id.; 110 U. S. 219; 185 U. S. 236. Contemporaneous construction is a rule of interpretation, but it is not an absolute one. It does not preclude an inquiry by the courts as to the original correctness of such construction. A custom of the department, however long continued, must yield to the positive language of the statute. Id.

Feod. lib. 1, tit. 10, (350) was warlike subjugation by force of superior military tactics." Wharton's Lex. voc. Tenure. But, whatever may be said of the historical fact, the etymology of the term itself, and its acknowledged use in feudal, Norman and early English law, demonstrate its original meaning to have been acquisition, without reference to the exercise of superior military force. The opinion of Blackstone is sustained by the high authority of Sir Henry Spelman, who has conclusively shown that "victory" and "military subjugation" are comparatively modern senses, which the word has illegitimately (ceu per adulterium,) acquired. Gloss. vocc. Conquestus, Questus. peFrom what cause, and by what process the term conquest came to lose its original, and acquire its modern sense, or, in other words, how and when it came to be disused in English law, and exclusively adopted as a word in ordinary language, cannot now be easily explained. Spelman adopts the opinion that, as the enforcement of the Conqueror's acquired right to the crown was accomplished by means of the signal victory obtained over Harold and the Saxons, the ideas of victory and subjugation become so strongly attached to his culiar title of Conquestor as gradually to obscure, and finally to supplant its original and proper meaning. That conqueror continued to be used after the Norman invasion in its technical sense, appears from the passage already quoted under that word, from the Monasticon Anglicanum. That the verb conquerer was used in the same sense as late as the time of Edward I. will appear from the passages given from Britton, under that word. As a general head of law, however, the same writer expresses the idea of acquisition by the act of the party, by the word purchas, the English form of which is still retained in modern law, in the same sense. Britt. cc. 33, 35, 36, 38. Conquest is used in the sense of subjugation, by King Henry IV. in his declaration of thanks on being made king. 1 How. St. Trials, 154. Lord Bacon appears to use the word in both senses, in the following passage: "When any king obtaineth by war any country whereunto he hath right by birth, he is ever in upon his ancient right, not upon his purchase by conquest." Arg. Case of the Postnati of Scotland, Works, iv. 356. In the Scotch law, the word conquest has come down to modern times, in its full original sense as a term of jurisprudence. See supra. An "heir of conquest" is said to be so called "because his right of succession is confined to the subjects which the ancestor himself had acquired or conquished by some singular title." Ersk. Inst. b. 3, tit. 8, § 14. See Heir of conquest. (351) (352) ( 353 ) st. 1, c. 6. 4 Bl. Com. 69.) Termes de la Ley. Cowell.

The precise date of its compilation is not known, but it seems to be certain that it was completed and in force as early as the eleventh century, and that during a succession of the ages that followed, it was received and obeyed as law by all the nations of Southern Europe. It has formed the basis of most of the subsequent collections of maritime laws, and is supposed to have still the force of law in the tribunals of Italy. 1 Duer on Ins. Introd.

Willcock's Office of Constable, Introd. On the whole, there seems little doubt that the office of constable, though partaking of many of the characteristics of the ancient Saxon peace officers, (the tithing man being little distinguishable from the petty constable,) is essentially of Norman origin. The military or half military character which has always belonged to it in England, (a decidedly Norman feature, as well as the name itself,) makes strongly in aid of this opinion. Under the statute of Winchester, it seems to have differed little from that of a modern militia inspector, and it is worthy of remark that the enrolment of the militia, providing them with quarters when called out, &c., form to this day in England part of the duties of a constable. Stat. 52 Geo. III. c. 38. See 12 Mod. 254. 5 Id. 427. Willcock's Off. Constable, 76, 78, 80. Dr. Wooddesson concurs in the opinion of Blackstone, that the officers now called constables derived that appellation at or after the statute of Winchester; although it is his conclusion that the office itself, in substance and effect, subsisted from immemorial antiquity in the English laws. 1 Wooddes. Lect. 152, 153. The opinion of Sir William Blackstone, that the modern office unites in itself those of the Saxon tithingman, and Norman constable, (properly so called,) is the one which perhaps best reconciles the different views which have been taken on this point of origin. 1 Bl.

Com. 109, note. His own words of definition are: "A contract or agreement is where a promise is made on one side, and assented to on the other; or where two or more persons enter into engagement with each other, by a promise on either side." Id. 108, 109. As to the word agreement, it may be observed that some word of the kind seems essential to constitute the basis of any definition of contract that can be attempted. Agreement appears to be the translation of conventio in the civil law definition of the term, but falls short of the original (a coming together) in expressiveness, besides being liable to the objection of being a synonyme (or nearly so,) of the word which it is selected to define. Its use, however, has the support of the highest authority in ancient and modern law. As to the idea of a consideration, it will be seen that it has been admitted into the best definitions of contract, both ancient and modern, (except that of Chief Justice Marshall,) that have been framed; and its materiality to complete the idea of a contract is forcibly shown by the circumstance, that in that class of contracts (those by specialty or under seal) in which no consideration in fact is required, one is always presumed by law, the form of the instrument being held to import a consideration. See 2 Kent's Com. 450, note.-The third objection of Mr. Stephen to the definition of Blackstone, that it takes no sufficient notice of the mutuality of a contract, has apparently more weight; although, from Blackstone's own analysis of his definition, it would seem that he intended the idea of mutuality to be conveyed by, and implied in the word agreement itself, which, in another passage, he describes as a mutual bargain or convention." 2 Bl. Com. 442. On the whole, notwithstanding these objections, the correctness of the definition of Blackstone remains essentially unimpeached, and it certainly enjoys the preferVOL. I. ence of the best authority. 2 Kent's Com. 499, 450. Story on Contracts, ubi supra. The modern use of the word contract, as a generic term for all sorts of obligations, (including those created by record and by specialty,) though established on high authority, seems to be an undue extension of the proper meaning of the term, and has thrown much difficulty in the way of accurate definition. Contract is obviously derived (through contractus, a term of the civil law,) from contrahere, to draw together; importing the same radical idea with agreement, but with a stronger expression of mutuality in the use of the particle con. See Agreement. Mutuality, indeed, is of its very essence; not only mutuality of assent, implying free and deliberate action of the parties in coming into the contract, but mutuality of act also,-mutuality in the things agreed to be done by the contract; each party engaging to do, or not to do certain things. There is, in Lord Coke's phrase, (though not in the etymological sense in which he used it,) act against act, (actus contra actum). 2 Co. 15. 7 Man. & Gr. 998, arg. and note. Thus, in the contracts of sale, bailment and for the performance of work, there are acts to be done by both parties; the one engaging to deliver the article or perform the work, and the other to pay the price, to use the article carefully, &c. So, in the contracts of partnership and marriage, the engagements are mutual. Engagements of this description, and no others, seem to come properly under the denomination of contracts. In a bond, on the other hand, there is none of this kind of mutuality; there is no act to be done by the obligee to make the instrument binding; the obligation is all upon the side of the obligor. In a judgment, there is not only no mutuality of act, but not even mutuality of assent; the obligation being fastened upon the party by the law, whether he wills it or not; judicium redditur in invitum. Hence, judgments have very properly been denied to be contracts, notwithstanding the doctrine of Blackstone, that a contract is, in such cases, implied. Lord Mansfield, 3 Burr. 1545. 1 Cowen's R. 316. Story, J. 1 Mason's R. 288. The impropriety of applying the term contract to bonds and judgments seems to be virtually admitted by Mr. Chitty, who uses obligation as an alternative word of description, in regard to both.

Budæus, cited in Cowell. * **This word is frequently written, and sometimes defined, as though it were derived from the Fr. compte, or old English accompt, an account. The error of this derivation, however, is easily seen on reference to the L. Lat. and L. Fr. forms, (contrarotulator, contrerouleur, from the latter of which the English controller is undoubtedly taken,) which show it to be compounded of contra, or contre, against, and rotulator, rouleur, an enroller; making its true signification to be the keeper of a counter-roll, i. e. a roll intended as a check upon another officer's roll or account. See the definition supra. The correctness of this etymology is strikingly confirmed by the composition of the word antigraphus; (Gr. dvri, against, and yoápev, to write,) the title of an officer who was charged with a similar duty in the Roman law. See supra. Controller of the pipe is defined by Cowell, to be an officer who "keeps a contra-rollment [or controlment] of the pipe." So, by the Stat. 3 Edw.
