Language contact is the process by which languages come into contact with each other and influence each other.

Trade and commerce, migration and colonization, and political and military conquest are all major factors that contribute to language contact.

Language convergence, language divergence, and language shift are all linguistic consequences of language contact.

Language convergence is the process by which languages become more similar to each other.

Language divergence is the process by which languages become more different from each other.

Language shift is the process by which speakers of one language adopt another language.

Increased cultural diversity, increased social inequality, and increased political conflict are all social and cultural consequences of language contact.

Language planning, language education, and language rights can all be used to manage language contact and promote positive outcomes.

Globalization has increased language contact by increasing the movement of people and goods across borders.

The spread of dominant languages, the loss of minority languages, and the homogenization of language are all challenges posed by globalization to language diversity.

Language planning, language education, and language rights can all be used to preserve language diversity in the face of globalization.

Language contact is likely to continue to increase in a globalized world as the movement of people and goods across borders continues to increase.

The rights of speakers of minority languages, the right to use one's own language, and the right to learn a new language are all ethical issues that arise from language contact.

Language contact can be used to promote peace and understanding by promoting intercultural communication, tolerance and respect for diversity, and cooperation and collaboration.

Books, articles, and websites are all resources that are available to help people learn about language contact.
