Grammar & vocabulary

What is an international organisation?

An international organisation is a body formed by several countries (called member states) that agree to cooperate on issues that cross national borders — peace and security, health, education, trade or the environment. These organisations exist because many problems cannot be solved by one country acting alone; they need coordinated, shared action. Cooperation between member states is usually formalised through a treaty, a formal written agreement that sets out the organisation's goals and rules.

The United Nations (UN)

The United Nations is the main global organisation whose general purpose is to maintain international peace and security, promote human rights, and encourage cooperation between countries on major global issues. It brings together almost all the world's countries as member states and provides a forum for diplomacy — the use of dialogue and negotiation, rather than conflict, to manage relations between countries. The UN is also associated with peacekeeping efforts and, in emergencies such as natural disasters or conflicts, with coordinating humanitarian aid — support such as food, shelter and medical care sent to help people in need.

Specialised agencies: UNESCO and the WHO

Some organisations work within the wider UN system but focus on one specific area. UNESCO (the United Nations Educational, Scientific and Cultural Organization) generally works on education, science and culture — for example, supporting access to education and protecting cultural and natural heritage sites around the world. The WHO (World Health Organization) generally works on global public health — for example, coordinating international responses to disease outbreaks and promoting access to healthcare. Both are examples of how international cooperation can focus on a specific field rather than covering everything at once.

Regional and economic organisations

Not all international organisations are global. Regional organisations, such as the African Union, bring together countries from the same region to cooperate on shared regional issues — for example, security, trade and development across the African continent. Economic organisations, such as the World Bank, generally work on financing development projects and reducing poverty by lending money and providing expertise to countries that need support, especially developing countries.

Key vocabulary

cooperation (noun) = countries or people working together toward a shared goal: "International cooperation was essential during the health crisis." sovereignty (noun) = a country's independent authority to govern itself: "Member states keep their sovereignty even when they join an international organisation." diplomacy (noun) = managing relations between countries through dialogue and negotiation: "The conflict was resolved through diplomacy rather than force." treaty (noun) = a formal written agreement between countries: "The countries signed a treaty to protect the shared river." member state (noun) = a country that belongs to an international organisation: "Morocco is a member state of the United Nations." humanitarian aid (noun) = support given to people in urgent need, such as after a disaster: "The organisation sent humanitarian aid to the flooded region."

Common mistakes

1

Confusing the United Nations with a single country or government — the UN is not a world government; it is an organisation of independent member states that choose to cooperate, and it cannot force a country to act without that country's agreement in most cases.

2

Mixing up 'sovereignty' and 'cooperation' — sovereignty means a country's independent authority to govern itself, while cooperation means countries working together voluntarily; joining an organisation does not automatically mean losing sovereignty.

3

Using 'treaty' and 'organisation' as if they were the same word — a treaty is a formal written agreement between countries, while an organisation is the institution (with staff, offices and programmes) that may be created or guided by one or more treaties.

4

Inventing specific statistics or dates about an organisation instead of describing its general role — for an exam answer, it is safer and more accurate to explain what an organisation generally does (its mission and area of work) than to guess exact figures.

5

Writing 'a UNESCO' or 'an UN' — organisation names formed from initials follow the pronunciation of the first sound: 'the UN' (pronounced 'the you-en') but 'UNESCO' is pronounced as a word, so 'a UNESCO programme', not 'an UNESCO programme'.

Worked example — Why organisations cooperate

Passage

"No single country can fight a global health crisis alone. That is why the WHO exists: to coordinate international cooperation on public health. Similarly, the United Nations relies on diplomacy, not force, to keep the peace between member states. When a natural disaster strikes, several countries and organisations often send humanitarian aid within days, guided by treaties and agreements signed long before the emergency happened. Regional bodies, like the African Union, add another layer of cooperation, focusing on the specific challenges of their region while still respecting each country's sovereignty."

Explanation

The passage links each organisation to its general role: the WHO to public health cooperation, the UN to diplomacy and peace between member states. "Humanitarian aid" appears in the context of emergency relief, and "treaties" is used to explain that cooperation is often based on formal prior agreements. The final sentence contrasts regional cooperation (the African Union) with the idea of sovereignty, showing that cooperating with others does not mean giving up independent authority over internal affairs.

3 practice exercises

Exercise 1

Easy

Match each organisation to its general area of work. Organisations: 1) UNESCO 2) WHO 3) UN 4) World Bank. Areas: a) international peace, security and human rights b) global public health c) education, science and culture d) financing development projects.

Show answer

1-c (UNESCO = education, science and culture), 2-b (WHO = global public health), 3-a (UN = international peace, security and human rights), 4-d (World Bank = financing development projects).

Exercise 2

Medium

Fill in each blank with the correct word from this list: cooperation, sovereignty, diplomacy, treaty, member state, humanitarian aid. 1) After the earthquake, several countries sent ___ to help affected families. 2) Morocco is a ___ of the United Nations. 3) The two countries signed a ___ to formally end the conflict. 4) International ___ allows countries to solve problems that no single country could solve alone. 5) Even within international organisations, each country keeps its ___ over its own internal affairs. 6) Ambassadors use ___ to resolve disagreements peacefully, without resorting to conflict.

Show answer

1) humanitarian aid 2) member state 3) treaty 4) cooperation 5) sovereignty 6) diplomacy.

Exercise 3

Hard

Answer each question in one or two complete sentences, using accurate, general information (no invented statistics). 1) Why was the United Nations created, in general terms? 2) What is the general difference between the role of the UN and the role of a specialised agency like the WHO? 3) Give one general reason why regional organisations, such as the African Union, are useful.

Show answer

1) The United Nations was created so that countries could cooperate to maintain international peace and security and to promote human rights, rather than resolving conflicts alone. 2) The UN deals broadly with peace, security and human rights among all member states, while a specialised agency like the WHO focuses on one specific area — in its case, global public health. 3) Regional organisations like the African Union are useful because they allow neighbouring countries with shared interests and challenges to cooperate more closely, for example on regional security, trade or development.

FAQ

What is an international organisation?

An international organisation is a body made up of member states (or, in some cases, other organisations) that work together, through diplomacy and cooperation, to deal with issues that cross national borders — such as peace and security, health, education or economic development — rather than issues one country can solve alone.

What is the difference between the UN, UNESCO and the WHO?

The United Nations (UN) is the broad, overarching organisation focused on international peace, security and human rights; UNESCO and the WHO are specialised agencies that work under the UN system on specific areas — UNESCO on education, science and culture, and the WHO (World Health Organization) on global public health.

Why do countries join international organisations if it means giving up some independence?

Countries join because many problems — disease outbreaks, climate change, armed conflict, economic instability — cross borders and cannot be solved by any single country acting alone; member states accept some shared rules and cooperation in exchange for collective benefits like humanitarian aid, shared resources, and a forum for diplomacy, while generally still keeping their core sovereignty over internal affairs.
