Definition
Yield carries distinct legal meanings depending on context. The three primary senses are:
1. (Property — feudal and conveyancing) To perform a service or render a payment due from a tenant to a lord or landlord. In the traditional law of real property, yield is the operative word in a reddendum — the clause in a deed or lease by which the grantor reserves something out of the thing granted, typically rent. The familiar formula "yielding and paying" introduces the reservation of rent in a lease.
2. (Finance and investment) The return produced by an investment, security, or financial instrument, expressed as a ratio of income to principal or market value. In securities regulation and transactional practice, yield is a term of art used in calculating bond returns, mortgage rates, dividend income, and related financial metrics.
3. (General legal usage) To give up, surrender, or concede a right, claim, or position. A party who yields a point in negotiation or argument surrenders it voluntarily. This sense overlaps with resignation or waiver in certain contexts.

Common Language
Modern common usage (Wiktionary): To give as a result or outcome; to produce or render. To produce as a return from an investment. To give way; to concede.
Historical common usage (Webster's 1913): To give in return for labor expended; to produce, as payment or interest on what is expended or invested; to pay. Also, to furnish, afford, render, or give forth.
The gap between common and legal meaning is narrowest here among all legal terms — yield in ordinary English already carries the senses of producing a return and of giving way. The distinctly legal dimension is the feudal-property sense: yield as the technical word of reservation in a conveyancing reddendum. A researcher reading a historical lease who encounters "yielding and paying" is reading a term of art, not mere ordinary English.

Recognized Forms
/SUBTYPES
Yielding and paying: The standard reddendum formula in lease drafting. The clause introduces the rent reserved, e.g., "yielding and paying therefore yearly the sum of..." This is the most legally significant use of yield in historical conveyancing instruments and remains vestigially present in modern lease forms.
Yield to maturity (YTM): In securities and finance law, the total anticipated return on a bond if held until it matures, accounting for all interest payments and the difference between purchase price and par value. A regulated calculation in securities disclosure contexts.
Current yield: Annual income from a security divided by its current market price. Used in disclosure documents and investment regulation.

Why It Matters in Research
Researchers face a term that performs very different work depending on the document type and era. Three practical traps:
First, chronological ambiguity in property records. In deeds and leases from the seventeenth through nineteenth centuries — and in historical forms persisting well into the twentieth — "yield" and "yielding and paying" are conveyancing terms of art tied to the reddendum. A researcher unfamiliar with this usage may misread the formula as mere verbal filler when it is in fact the operative reservation of rent or service. The phrase is load-bearing in the instrument.
Second, the feudal residue. Black's definition goes directly to the feudal-tenure root: yield as performance of service due by a tenant to his lord. This context is largely obsolete in modern freehold property law but remains essential for reading historical English and early American title documents, manorial records, and colonial land grants. Corpus sources touching land tenure before the nineteenth century will use yield in this strict feudal sense.
Third, the financial meaning is modern and jurisdiction-sensitive. Yield as a financial metric is a creature of securities regulation and modern banking law. It appears extensively in regulatory filings, bond indentures, mortgage disclosure forms, and consumer financial instruments. Researchers moving between historical property documents and modern financial instruments need to recognize that they are working with the same word doing fundamentally different work.
The Rapalje & Lawrence entry offers only a page reference with no substantive definition, which signals that mid-nineteenth-century American practice treated yield as sufficiently understood from common usage and conveyancing tradition to need no extended treatment.

Historical Dictionary Support
The historical dictionaries converge on yield's core property-law meaning but with varying emphasis. Bouvier reduces it to its most abstract legal sense: "to give as claimed of right; to resign." Burrill is more expansive, listing the Latin equivalents reddere and cedere, and includes the senses of surrendering, giving way, and giving place — reflecting the range of contexts in which the term appeared in instruments and pleadings.
Black focuses most precisely on the conveyancing application: yield in real property law as performance of service due by a tenant, and as the word of art in a reddendum. This is the most practically useful historical definition for researchers working with deeds and leases.
What the historical dictionaries do not cover is the financial sense. None of the shelf sources addresses yield as an investment return metric. This is expected — that meaning developed primarily through nineteenth- and twentieth-century financial practice and securities regulation, well after most of these sources were written or compiled. Researchers relying solely on historical dictionaries for yield in a financial-instrument context will find no guidance there.

Jurisdictional Note
The conveyancing sense of yield is rooted in English common law tenure doctrine and traveled to American practice through colonial land grants and inherited deed forms. It remains vestigially present in American lease drafting but carries no independent feudal-tenure significance in any American jurisdiction today. The financial meaning of yield is addressed in federal securities regulation and varies in application between debt instruments, equity, and real estate finance contexts.
