The language the government writes in.

Plain, practitioner definitions across real-time, alternative, market, and satellite data - and machine learning.

Working definitions for anyone who has just met a term in an article and needs it to make sense of the next sentence. Where a word has an exact meaning in statute or regulation - a final rule is already in force, a continuing resolution is not a budget - that is the meaning given. Every definition links to the ones it depends on, so you can follow an idea rather than look up one word at a time.

Federal writing is precise, and almost none of it is plain.

The federal government writes with real precision, in a vocabulary that assumes you already have it. A notice of proposed rulemaking is a specific stage with specific consequences; a continuing resolution is not a budget; an interim final rule is already in force. Miss one of those and you have misread the document, not just the tone.

So these are working definitions, written for someone who has just met the term in an article and needs it to make sense of the next sentence. Where a word has an exact meaning in statute or regulation, that is the meaning given.

Terms are added when an article needs one, which is why this list grows unevenly rather than alphabetically. Each definition links to the ones it depends on, so a reader can follow the chain without leaving to search for the next word.

How a definition connects4 pages

The term you landed on

Federal Register

The daily journal of the US government, where agencies publish proposed and final rules, notices, and presidential documents.

Linked from inside the definition

Notice of proposed rulemaking

An agency's formal proposal of a new rule, published for public comment before anything becomes binding.

Final rule

The binding version of a regulation, published after the comment period, with an effective date and the agency's response to comments.

Code of Federal Regulations

The permanent, subject-organised codification of federal agency rules - what the Federal Register's daily output becomes.

Every definition links to the terms it depends on, so a reader who arrived for one word can follow the argument instead of leaving to search for the next one.

Three kinds of entry.

Terms with a legal meaning

Where a word is defined in statute or regulation, the entry gives that definition and names the authority. These are the ones where an everyday reading is actively misleading.

Institutions and instruments

What a body actually does and what its output binds - an agency, a committee, a court, or a document type like a notice of proposed rulemaking.

Terms of art

Words the federal government uses precisely and everyone else uses loosely. The entry says what the precision is and where it stops mattering.

Lawmaking

Cloture

The Senate procedure for ending debate on a measure, requiring sixty votes for most legislation.

Budget reconciliation

A fast-track process letting certain budget legislation pass the Senate by simple majority, immune to the sixty-vote threshold.

Markup

The committee session where a bill is amended line by line and voted on before it can reach the floor.

Conference committee

A temporary joint panel that reconciles differing House and Senate versions of the same bill into one text.

Enrolled bill

The final, identical text passed by both chambers, prepared for signature and, once signed, the law itself.

Pocket veto

A bill that fails because the president neither signs nor returns it while Congress is adjourned.

Rulemaking

Federal Register

The daily journal of the US government, where agencies publish proposed and final rules, notices, and presidential documents.

Notice of proposed rulemaking

An agency's formal proposal of a new rule, published for public comment before anything becomes binding.

Final rule

The binding version of a regulation, published after the comment period, with an effective date and the agency's response to comments.

Code of Federal Regulations

The permanent, subject-organised codification of federal agency rules - what the Federal Register's daily output becomes.

Docket

The numbered file that holds everything submitted in one rulemaking or one court case, and the public record a decision has to answer to.

Administrative Procedure Act

The 1946 statute that governs how federal agencies make rules and how courts review them.

Interim final rule

A rule that takes effect immediately, with public comment collected after the fact rather than before it.

Effective date

The day a rule starts to bind, which is rarely the day it was published and rarely the day compliance is measured.

Guidance document

An agency statement explaining how it reads a rule, issued without notice and comment and formally binding on no one.

OIRA review

The White House review that most significant draft rules must clear before an agency may publish them.

Unified Agenda

The semiannual published list of regulations each federal agency expects to work on, with target dates.

Congressional Review Act

A 1996 statute letting Congress overturn a recently finalised agency rule by simple majority, with the president's signature.

Money and the Budget

Continuing resolution

A stopgap funding measure that keeps federal agencies operating at existing levels when Congress has not passed its appropriations bills.

Appropriations

The legislation that actually provides money to federal agencies, distinct from the authorisation that permits a programme to exist.

Federal Open Market Committee

The Federal Reserve body that sets US monetary policy, including the federal funds rate target, at eight scheduled meetings a year.

Federal funds rate

The overnight rate at which banks lend reserves to one another, and the Federal Reserve's principal policy instrument.

Discount rate

The rate the Federal Reserve charges banks that borrow directly from it, set by the regional Reserve Banks rather than by the FOMC.

Beige Book

The Federal Reserve's qualitative summary of economic conditions in each of the twelve districts, published before each FOMC meeting.

Debt limit

The statutory ceiling on total federal borrowing, which constrains paying for spending Congress has already approved.

Sequestration

Automatic across-the-board spending cuts triggered when statutory budget limits are breached.

Rescission

A proposal to cancel budget authority Congress has already provided, which lapses unless Congress approves it.

Oversight and the Courts

Inspector general

An independent watchdog inside a federal agency, empowered to audit and investigate it and to report findings to Congress.

Chevron deference

The former doctrine requiring courts to defer to an agency's reasonable reading of an ambiguous statute, overruled in 2024.

Major questions doctrine

The principle that an agency needs clear congressional authorisation before deciding a question of vast economic or political significance.

Vacatur

A court order setting aside an agency action so that it has no legal effect, ordinarily nationwide.

Stay

A court order pausing the effect of a rule or a judgment while litigation continues, deciding nothing on the merits.

Amicus curiae

A friend of the court: a non-party permitted to file a brief offering argument or expertise in a pending case.

Slip opinion

A court's decision as first issued, before official publication, and the version everyone actually reads.
