International mostly means something (a company, language, or organization) involving more than a single country. The term international as a word means involvement of, interaction between or encompassing more than one nation, or generally beyond national boundaries. For example, international law, which is applied by more than one country and usually everywhere on Earth, and international language which is a language spoken by residents of more than one country.
International Studies (IS) generally refers to the specific university degrees and courses which are concerned with the study of ‘the major political, economic, social, and cultural issues that dominate the international agenda’. Predominant topics are politics, economics and law on a global level. The term itself can be more specifically defined as ‘the contemporary and historical understanding of global societies, cultures, languages and systems of government and of the complex relationships between them that shape the world we live in’. The terms and concepts of International Studies and international relations are strongly related; however, International relations focus more directly on the relationship between countries, whereas International Studies can encompass all phenomena which are globally oriented.
