Definition
The completion or fulfillment of a thing. In law, the term carries two primary meanings:
1. GENERAL: The bringing of any matter to its final and complete state. Used broadly to describe the point at which a transaction, agreement, or legal relationship becomes fully effective or concluded.
2. MARRIAGE LAW: The completion of a marriage by the first act of sexual intercourse between the spouses following the marriage ceremony. Consummation is legally significant in several contexts, including the validity of a marriage, grounds for annulment, and the distinction between a marriage that is merely ceremonial and one that is fully operative.

Common Language
Modern common usage (Wiktionary): The act of consummating, or the state of being consummated; completion. Also specifically: the first act of sexual intercourse in a relationship, particularly following marriage; the achievement of perfection; termination or end.
Historical common usage (Webster's 1913): The act of consummating, or the state of being consummated; completed; completion; perfection; termination; end. "Consummation of marriage: completion of the connubial relation by actual cohabitation."
The common and legal meanings align closely here, but the gap worth noting is one of legal consequence. Ordinary usage treats consummation primarily as a descriptive word for completion. Legal usage, particularly in marriage and annulment doctrine, makes consummation a factual threshold with jurisdictional and doctrinal weight — the presence or absence of consummation can determine whether a marriage may be annulled rather than dissolved by divorce, and historically affected property rights and the status of children.

Common Confusion
CONSUMMATION vs. SOLEMNIZATION: Solemnization refers to the formal ceremony by which a marriage is performed; consummation refers to the subsequent physical act that, in many legal systems, completes the marital relationship. The two are distinct events. A marriage may be solemnized but not consummated, which in some jurisdictions renders it voidable.
CONSUMMATION vs. RATIFICATION (in contract): In transactional contexts, consummation is sometimes loosely used to mean closing or execution. Researchers should distinguish this from ratification, which has a precise legal meaning involving the subsequent approval of a prior act. The terms are not synonymous, and conflation can distort the operative moment of a contract's legal effect.

Why It Matters in Research
Researchers working in family law, ecclesiastical law, or early Anglo-American marriage doctrine will encounter consummation as a term with substantial legal freight. Its significance varies sharply across time and jurisdiction, which creates traps in historical sources.
In older English law and canon law traditions carried into early American practice, consummation was not merely incidental to marriage — it was the act that perfected the marital bond and, in some formulations, was what converted a marriage per verba de futuro (a promise to marry) into a binding marriage per verba de praesenti. This doctrinal link has largely dissolved in modern American law, but it shapes the vocabulary of older treatises and case reporters. Reading 19th-century marriage and annulment decisions without this background produces confusion about why courts are analyzing a fact that seems private and extralegal.
In annulment jurisprudence, the distinction between void and voidable marriages often turned on consummation. Some grounds for annulment (such as incapacity to consummate) could only be raised before consummation occurred, or were extinguished by it. Historical case law on this point must be read with attention to which rule the jurisdiction was following.
In mortgage and consumer lending law, a narrower modern usage appears in federal regulations under the Truth in Lending Act and Regulation Z, where consummation refers to the moment a consumer becomes contractually obligated on a credit transaction. This meaning is technical, time-specific, and entirely distinct from the marriage law usage — researchers crossing between these bodies of law should not assume the term carries the same meaning.
The corpus connection between consummation and annulment, canon law, and ecclesiastical court records is strong. Researchers tracing marriage validity doctrine through ecclesiastical or early probate materials should treat consummation as a keyword with doctrinal significance, not merely a descriptive term.

Historical Dictionary Support
Both Black's editions define consummation consistently and briefly: "the completion of a thing; the completion of a marriage between two affianced persons by cohabitation." The second edition adds a California citation (Sharon v. Sharon) that grounds the marriage law usage in American case law.
Webster's 1913 confirms that the marriage-specific meaning was well established in general usage by the late 19th century, not merely a legal term of art. The Shakespearean quotation ("'Tis a consummation devoutly to be wished") in Webster's is a useful reminder that the broader meaning — a wished-for completion or end — was the dominant ordinary usage, with marriage consummation as a recognized but subordinate application.
What the historical dictionaries do not address is the doctrinal significance of consummation in canon law and its inheritance by common law courts. Black's entries treat the term almost in passing, without indicating that its presence or absence could determine the operative legal category of a marriage. Researchers relying solely on the dictionary definitions would miss the doctrinal weight the term carries in annulment and marriage validity cases.

Jurisdictional Note
The legal relevance of consummation to marriage validity varies by jurisdiction and has diminished significantly in modern American law. Most U.S. states no longer treat non-consummation as an independent ground for annulment, though some retain it in limited form. English and ecclesiastical law historically placed greater weight on this element. Researchers examining 19th-century or earlier sources should not assume modern rules apply.
