How to use the acronym decoder

  1. Type the acronym or the name

    Search by the letters (DISEC, unhcr, A/RES) or by words from the full name (refugees, speakers list). Case, spaces and punctuation are ignored, and the closest match comes first.

  2. Narrow it by category

    Pick UN organs and committees, UN agencies, Model UN procedure, treaties and policy terms, other organizations, or US Model UN conferences to see only that group.

  3. Browse the A to Z index

    With the search box empty, every acronym is listed alphabetically. Jump to a letter from the index to scan a whole section of your background guide at once.

  4. Read the note, then research the body

    Many entries say what the body does or how the term is used in committee. When an acronym matters to your topic, research what that body has actually done before you cite it.

The General Assembly's six Main Committees

Many large Model UN committees simulate one of these. Conferences use the acronym, the number or both, so “GA1”, “First Committee” and “DISEC” are the same room.

CommitteeAcronymCovers
First CommitteeDisarmament and International Security CommitteeDISECDisarmament and international security
Second CommitteeEconomic and Financial CommitteeECOFINEconomic and financial questions

Acronyms delegates mix up

Getting one of these wrong in a speech costs you credibility with the dais. Learn the difference before committee starts.

UNHRC vs UNHCR
UNHRC is the Human Rights Council, the intergovernmental body of member states in Geneva. UNHCR is the UN Refugee Agency. The letters are one swap apart, and mixing them up in a speech is a common slip.
UNHRC vs OHCHR
The Human Rights Council is made up of member states and passes resolutions. OHCHR, the Office of the High Commissioner for Human Rights, is part of the Secretariat and supports that work.
ICJ vs ICC
The International Court of Justice is a principal organ of the UN and hears disputes between states. The International Criminal Court is a separate, treaty-based court that tries individuals.
P5 vs E10
The P5 are the five permanent members of the Security Council, each with a veto on substantive decisions. The E10 are the ten members elected for two-year terms, without a veto.
PP vs OP
Preambular paragraphs open a resolution and give its reasons. Operative paragraphs are numbered and say what the body does. In delegate chat, PP can also mean position paper, so check which one someone means.
Mod vs unmod
A moderated caucus is formal debate on a narrow sub-topic, with the chair calling on speakers. An unmoderated caucus is informal time out of your seat to negotiate and write.
A/RES vs S/RES
The prefix on a UN document symbol tells you who adopted it: A/RES for the General Assembly, S/RES for the Security Council. Cite the full symbol when you point to past action.

Using acronyms in papers and speeches

In a position paper, write the full name the first time, with the acronym in brackets: “the Office for the Coordination of Humanitarian Affairs (OCHA)”. After that, the acronym alone is fine. When you point to past action, cite the document symbol, such as an A/RES or S/RES number, rather than “a UN resolution”.

In a speech, fewer is better. The committee's own name and household acronyms like UNSC, WHO or NATO are safe. For anything a newer delegate might not know, say the name. You have a minute or so, and a room that is decoding your acronyms is not following your argument.

In a resolution, follow your conference's format guide. Many ask for full names in the clauses themselves, and clauses are often read aloud when a draft is introduced, so spelled-out names are easier for the room to follow.

Before you cite a body, check what it actually does. Naming UNEP in a disarmament speech, or asking the ICJ to prosecute an individual, tells the chair you learned the acronym but not the institution.

Frequently asked questions

What do DISEC, ECOFIN, SOCHUM and SPECPOL stand for?
They are the first four Main Committees of the UN General Assembly. DISEC is the Disarmament and International Security Committee (First Committee). ECOFIN is the Economic and Financial Committee (Second). SOCHUM is the Social, Humanitarian and Cultural Committee (Third). SPECPOL is the Special Political and Decolonization Committee (Fourth). The Fifth and Sixth Committees, Administrative and Budgetary and Legal, have no widely used acronym.
What is the difference between UNHRC and UNHCR?
UNHRC is the UN Human Rights Council, an intergovernmental body of member states based in Geneva. UNHCR is the UN High Commissioner for Refugees, the UN Refugee Agency. They are easy to confuse because the letters are nearly the same, so double-check which one your committee and your sources mean.
What is the difference between the ICJ and the ICC?
The International Court of Justice (ICJ) is the UN's principal judicial organ. It settles disputes between states and gives advisory opinions. The International Criminal Court (ICC) is an independent court created by the Rome Statute that tries individuals for crimes such as genocide and war crimes. It is not a UN organ.
What do GSL, mod and unmod mean in Model UN?
GSL is the General Speakers' List, the queue of delegates waiting to give formal speeches. Mod is short for moderated caucus, a timed debate on a narrow sub-topic in which the chair calls on speakers. Unmod is short for unmoderated caucus, informal time out of your seat to negotiate and draft. Exact rules differ by conference, so check your rules of procedure.
What do PP and OP mean in a resolution?
PP means preambular paragraph and OP means operative paragraph. Preambular paragraphs set out the context and reasons for a resolution. Operative paragraphs are numbered and state what the body decides, requests or recommends, so OP3 is the third operative clause.
Should I use acronyms in my position paper or speech?
In writing, give the full name the first time followed by the acronym in brackets, then use the acronym. In speeches, the committee's own name and very common acronyms such as UNSC or WHO are fine, but say the full name of anything less familiar. The chair and other delegates may not know it, and a speech is harder to reread than a page.
Is the acronym decoder free?
Yes. It is free, needs no account and runs in your browser. If you want to research what a UN body has actually done on your topic, a free Model Diplomat account includes 200 searches on day one, then 50 a day.
