Definition
Affirmance has three distinct legal meanings, each operative in a different procedural context.
1. Appellate affirmance. The formal act by which an appellate court confirms, ratifies, or upholds the judgment, order, or decree of a lower court after review. When an appellate court affirms, it declares the lower court's decision correct and leaves it standing. This is the most common modern usage.
2. Affirmance of a voidable act. The confirmation or adoption of an act that was voidable — not void — by the party who has the power to avoid it. A contract entered into during minority, for example, is voidable by the minor upon reaching majority; if instead the now-adult party accepts benefits, performs obligations, or otherwise treats the contract as binding, that conduct constitutes affirmance. Affirmance in this sense extinguishes the right to avoid.
3. Affirmance of a prior law or judgment. The legislative or judicial ratification of a former enactment or ruling, signaling that the prior instrument remains in force. This usage is largely archaic but appears in older statutes and treatises.

Common Language
Modern common usage (Wiktionary): The act of affirming; affirmation generally. Also, a decision upholding the decision of a lower court or agency.
Historical common usage (Webster's 1913): Confirmation; ratification. Also a strong declaration or affirmation.
The gap that matters: Ordinary usage treats "affirmance" and "affirmation" as near-synonyms for any act of confirming or declaring something. In law, the term carries precise procedural weight in two distinct directions — appellate procedure and contract law — and the consequences in each context are substantive, not merely rhetorical. A researcher encountering "affirmance" in a historical source must determine which of the three legal senses is operative before drawing conclusions.

Common Confusion
Affirmance, ratification, and confirmation are frequently used interchangeably in both ordinary and older legal writing, but they are technically distinct.
Affirmance applies when a party who personally performed a voidable act later validates it by their own conduct or declaration.
Ratification applies when a party validates an act performed by another on their behalf — typically arising in agency law.
Confirmation is used where a doubtful or defective authority was exercised, and a subsequent act removes the defect or doubt.
Bouvier's draws this distinction explicitly. Burrill likewise treats affirmance and confirmation as related but separate. The confusion compounds in historical sources, which often use the terms without precision. Researchers analyzing contract disputes, agency relationships, or real property conveyances in pre-twentieth-century materials should not assume these terms are interchangeable.
A separate confusion: dismissal of an appeal for want of prosecution is not an affirmance. The lower court judgment may survive, but the appellate court has not reviewed or confirmed its correctness. Black's flags this point directly; Rapalje & Lawrence cite authority for the same proposition.

Why It Matters in Research
The three-meaning problem is the central research hazard. An index entry for "affirmance" in a digest or treatise may lead a researcher to appellate procedure materials, contract avoidance doctrine, or legislative history, depending on context. Confirm which sense is operative before following a cross-reference chain.
In appellate research, affirmance is the outcome that terminates review in the lower court's favor. It is not a finding that the lower court's reasoning was correct — only that the result stands. Researchers examining what an appellate court actually held should read the opinion itself, not rely on the docket notation "affirmed."
In contracts research, affirmance of a voidable contract is irreversible once made. This creates a trap in historical sources: courts and treatise writers sometimes describe a party as having "affirmed" a contract through conduct without using the word explicitly. The legal consequence — loss of the avoidance right — may follow from acts (accepting performance, making payments, remaining silent after gaining full knowledge) rather than from any formal declaration.
The legislative-affirmance meaning appears in English statutes and early American statutory compilations. Burrill cites the statute 8 Hen. VI. c. 12 as an example. Researchers working with pre-constitutional or early republic legislative materials may encounter this usage where a modern reader would expect "confirmed" or "reenacted."
Corpus connections: affirmance in appellate procedure connects directly to the mechanics of AFFIRM, REVERSAL, REMAND, and MANDATE. Affirmance of voidable acts connects to RATIFICATION, AVOIDANCE, VOIDABLE CONTRACT, and DISAFFIRMANCE — the last being the mirror image of affirmance in minor's contract doctrine.

Historical Dictionary Support
The historical sources converge on the core meanings but differ in emphasis and completeness.
Black's (both editions) and Burrill treat appellate affirmance as primary and give the voidable-act meaning as secondary. Bouvier inverts this emphasis, leading with the voidable-act definition and treating the distinction from ratification and confirmation as the central analytical point — a reflection of Bouvier's stronger orientation toward private law doctrine. Rapalje & Lawrence is characteristically terse, giving only the voidable-act definition and a single case citation.
All sources that address the appellate sense agree that dismissal for want of prosecution is not an affirmance — an important limiting principle that appears consistently across the shelf.
The legislative-affirmance meaning is present in Burrill (citing Cowell and Blount) and carried forward in both Black's editions, but none of the sources develop it substantively. It is effectively a fossil meaning preserved for completeness.
Webster's 1913 is useful here because it captures the ordinary-language background: Bacon's usage ("in affirmance of the common law") illustrates the legislative sense and shows how close ordinary and legal usage could be in that tradition. The modern divergence between common and legal usage is primarily a product of the word's legal senses becoming more technically precise over time.

Jurisdictional Note
The voidable-act sense of affirmance, particularly in minor's contracts, is universally recognized across American jurisdictions but the specific acts sufficient to constitute affirmance — and the knowledge required — vary by state common law and statute. Researchers should not assume that a nineteenth-century treatise statement about what conduct constitutes affirmance reflects current doctrine in a target jurisdiction.
