Definition
To depose carries two distinct legal meanings that share only the word itself.
1. (Procedural) To give sworn testimony outside of court, typically in a deposition proceeding; to make statements that are recorded in writing and sworn to by the witness. In modern practice, the term also encompasses the act of questioning a witness in a deposition — a lawyer deposes a witness. The person giving such testimony is called the deponent.
2. (Public law) To remove a sovereign, official, or other person holding public authority from their position by force, legal process, or formal act — typically against that person's will. Used most naturally of monarchs and heads of state, but applicable to any holder of public office stripped of authority.
These two meanings are unrelated in function and arise in entirely different legal contexts. Researchers should read the surrounding text carefully to confirm which sense is intended.

Common Language
Modern common usage (Wiktionary): To remove a leader from high office without killing them; to give evidence or testimony during a deposition; to interrogate a witness during a deposition; to put down or lay aside (archaic).
Historical common usage (Webster's 1913): To remove from a throne or high station; to dethrone or deprive of office. Also, to testify under oath. Earlier senses — to lay down, to let fall, to deposit — were already marked obsolete by 1913.
The ordinary language senses track the legal meanings reasonably well, but with one gap worth noting: common usage treats "depose a witness" as something a lawyer does to someone else, while historical legal usage — preserved in affidavit formulas — treats the witness as the active party ("deposes and says"). Researchers encountering old affidavits and pleadings should recognize that the deponent is the actor, not the subject.

Common Confusion
The procedural sense of depose (to give or elicit sworn testimony) is sometimes conflated with testify, but the terms are not interchangeable. Testimony occurs at trial; a deposition occurs outside court, typically during discovery. In older sources, the distinction is less stable — Burrill notes that depose in ancient practice simply meant to testify as a witness in any setting. Black's (both editions) flags this shift explicitly, distinguishing ancient from modern usage. Researchers working with pre-nineteenth-century materials should not assume "deposed" means a formal pre-trial deposition in the modern sense.
The public-law sense (removal from office) should not be confused with impeachment. Impeachment is a formal legislative process with defined procedural steps; deposition in the public-law sense is broader and may occur through political, military, or legal means without any legislative proceeding.

Why It Matters in Research
The dual meaning of depose creates genuine indexing and search hazards in the Law Mind corpus. A query for "depose" or "deposed" in a political or constitutional context will surface sovereign removal materials; the same query in a civil procedure or evidence context will surface deposition materials. The terms overlap most dangerously in sources that treat both topics without clear section breaks — watch for this in older encyclopedias and treatises that organize by alphabetical headword rather than by subject.
The affidavit formula "being duly sworn, deposes and says" appears with high frequency across the corpus in pleadings, exhibits, and sworn statements. Researchers should recognize this as a standardized formula, not a term of art requiring interpretation each time it appears. Its presence signals a sworn written statement, not a deposition in the modern discovery sense.
For the public-law meaning, usage is concentrated in constitutional law materials, treatises on sovereignty and political theory, and historical materials involving royal succession, colonial governance, and military occupation. Bouvier cites Wolffius's Institutiones for this sense, reflecting the term's roots in natural law and continental jurisprudence — a reminder that the public-law sense carries intellectual lineage distinct from common law procedure.
Jurisdictional divergence matters primarily for the procedural sense: the mechanics of depositions vary across federal and state practice, and historical sources from English practice may use depose in ways that do not map cleanly onto American discovery procedure.

Historical Dictionary Support
The historical dictionaries are in agreement on both meanings and present no significant divergence. Black's (both editions) and Bouvier's each list both senses — procedural testimony and removal from office — in that order, treating them as parallel definitions under a single headword. Burrill focuses almost entirely on the procedural sense, adding the practical detail that depose appears as a term of art in affidavit formulas, which the other dictionaries do not emphasize.
Burrill's note that in "old practice" depose meant to testify as a witness generally — before the modern deposition procedure crystallized — is the most historically useful gloss in the set. Black's reinforces this by distinguishing "ancient usage" (testify as a witness, in any setting) from "modern usage" (make a deposition, a specific out-of-court procedure). Neither Black's nor Bouvier's traces the public-law sense beyond a brief definition, and neither engages with the continental or natural-law origins that explain why the term carries this meaning at all.
What the historical dictionaries collectively miss: they do not address the transitive modern sense — a lawyer deposes a witness — where the questioner, not the speaker, is the grammatical subject. This usage is standard in contemporary American practice but would have been unfamiliar or awkward to the compilers of these sources, for whom the deponent was always the actor.

Jurisdictional Note
The procedural sense of depose is governed by court rules that vary by jurisdiction. Federal practice is controlled by the Federal Rules of Civil Procedure; state rules differ, sometimes substantially, on notice requirements, duration limits, and permissible scope. Historical English practice did not have depositions in the American discovery sense, so English common law sources use depose more loosely to mean any sworn oral or written statement.
