Definition
An expenditure is the actual payment or disbursement of money. It refers to money that has been paid out, not merely obligated or accrued.
In most legal contexts, the term carries a narrow, cash-out meaning: an expenditure occurs when funds are actually transferred, not when a debt is incurred. This distinguishes expenditure from related concepts such as liability or obligation. A party may incur a liability — becoming legally obligated to pay — without yet making an expenditure. The expenditure occurs only upon actual payment.
In statutory and regulatory contexts, the definition is often expanded or specialized. Campaign finance law, tax law, and government appropriations law each impose their own definitions of what qualifies as an expenditure, and researchers should not assume the general meaning controls in any of these areas.

Common Language
Modern common usage (Wiktionary): The act of expending or paying out; the amount expended or paid out.
Historical common usage (Webster's 1913): The act of expending; a laying out of money; disbursement; also, that which is expended or paid out.
The common meaning and the legal meaning are largely aligned in ordinary usage — both treat an expenditure as money actually paid. The legal significance lies in where the common meaning falls short: law frequently requires a sharp distinction between incurring a liability and making an expenditure, and between expenditures and other financial events such as accruals, encumbrances, or in-kind transfers. In regulated contexts — particularly campaign finance and government appropriations — the word carries statutory definitions that may diverge substantially from plain English.

Common Confusion
Expenditure vs. Expense: These terms are often used interchangeably in ordinary speech, but they are not always synonymous in law. An expense is typically an item charged against revenue or income — an accounting concept. An expenditure is the outflow of cash or funds. Anderson's flags that "expenses" varies in meaning with context, the intent of parties, and the circumstances of particular cases, especially in testamentary instruments. Researchers should not assume these terms are interchangeable in the document they are reading.
Expenditure vs. Liability: Incurring a liability means becoming legally obligated to pay. Making an expenditure means actually paying. The two events are legally distinct and often occur at different times. This distinction matters in appropriations law, tax timing, and accounting-based legal tests.
Expenditure vs. Contribution (Campaign Finance): In campaign finance law, expenditures and contributions are separate, regulated categories with different constitutional treatment following Buckley v. Valeo and subsequent decisions. An expenditure is a disbursement made to advocate for or against a candidate or cause; a contribution is a transfer to a candidate or committee. Conflating them in research leads to serious analytical error.

Why It Matters in Research
The central research trap with "expenditure" is assuming the general definition controls when the source in hand arises from a statutory or regulatory scheme with its own definition. Always check whether the governing statute or regulation provides an express definition before applying the common-law meaning.
In campaign finance materials, this is critical. The Law Mind corpus contains substantial material on how the definition of "expenditure" has evolved from FECA through Citizens United and beyond. The constitutional treatment of expenditure limits (subject to First Amendment scrutiny) versus contribution limits (more readily regulated) turns on the boundary between these two concepts — a boundary that courts have redrawn repeatedly. Corpus materials from the 1970s will reflect the post-Buckley framework; materials from the 2010s must be read against the Citizens United line of decisions.
In government appropriations and public finance materials, "expenditure" often operates within a defined budgetary cycle — the distinction between appropriations, obligations, and expenditures is technically precise and varies by jurisdiction and era. Nineteenth-century materials may use the term more loosely.
In probate and testamentary contexts, Anderson's warning about "expenses" applies equally here: courts have construed expenditure language in wills and trusts with close attention to testamentary intent, and historical cases may not map cleanly onto modern statutory defaults.
Tax law adds another layer. The timing of expenditures — when a payment is made versus when a liability is accrued — affects deductibility and basis calculations. The cash method and accrual method of accounting each assign legal significance to different moments in the payment cycle.

Historical Dictionary Support
Anderson's Dictionary of Law offers a compact but useful entry: an expenditure is an actual payment of money, and the entry draws the critical distinction between incurring an expenditure and incurring a liability. This distinction is the dictionary's most useful contribution and remains accurate as a baseline rule.
Anderson's separately notes that "expense" and "expenses" vary in meaning depending on the intent of parties and testators, and cross-references costs — a signal that researchers should read these terms contextually rather than assuming definitional uniformity across documents of the same period.
What historical dictionaries generally miss is the statutory proliferation that has given "expenditure" specialized meanings in campaign finance, tax, and public appropriations law. Anderson's entry reflects a common-law era in which the word operated primarily as a financial term of art rather than a regulated category. Modern researchers using nineteenth- or early-twentieth-century dictionary definitions as interpretive anchors for contemporary statutory materials risk misreading the source.
