In linguistics, borrowing is the process by which a word from one language is adapted for use in another.
Loanwords are words adopted by the speakers of one language from a different language (the source language); can also be called a borrowing.
Borrowing is a consequence of cultural contact between two language communities.
Language contact is the social and linguistic phenomenon by which speakers of different languages (or different dialects of the same language) interact with one another, leading to a transfer of linguistic features.
Language contact often occurs along borders or as a result of migration.
