The correct spelling of the word is actually "countries". It is pronounced as /ˈkʌn.triz/ with stress on the first syllable. This word refers to a nation or state, typically one that is politically organized under a government. Misspelling this word as "coutries" might be a common mistake but it is important to always use the correct spelling in order to convey the intended meaning accurately. Nonetheless, it is always good to proofread your work to spot any spelling errors.
I apologize, but the term "coutries" does not appear to have a recognized dictionary definition. It is possible that you may have intended to refer to the word "countries," which has a well-established definition. In that case, here is a 200-word definition for "countries":
A country is a distinct geographical and political entity characterized by a defined territory, a permanent population, a government, and the capacity to enter into relations with other countries. It is generally recognized as a sovereign state and possesses its own system of laws and regulations. Countries are diverse in terms of size, population, natural resources, culture, and government structure.
In many cases, countries have borders that separate them from neighboring nations, although landlocked countries do not have direct access to the sea. The term "country" is often used interchangeably with "nation" or "state."
Each country is governed by a specific political system, which may vary from democratic to autocratic, from monarchy to republics. Countries typically have their own flag, national anthem, and distinct symbols that represent their identity. They often have their own currency, language, and culture, contributing to their individual national character.
Countries play a significant role in international affairs, engaging in diplomatic relations, trade agreements, and cooperation in various fields. They are members of international organizations such as the United Nations, contributing to global peace, development, and cooperation.
