A loanword (also a loan word, loan-word, or borrowing) is a word at least partly assimilated from one language (the donor language) into another language (the recipient language, also called the target language). This is in contrast to cognates, which are words in two or more languages that are similar because they share an etymological origin; and calques, which involve translation. Loanwords from languages with different scripts are usually transliterated (between scripts), but they are not translated. Additionally, loanwords may be adapted to the phonology, phonotactics, orthography, and morphology of the target language (as for example through the law of Hobson-Jobson). When a loanword is fully adapted to the rules of the target language, it is distinguished from native words of the target language only by its origin. However, often the adaptation is incomplete, so loanwords may conserve specific features distinguishing them from native words of the target language: loaned phonemes and sound combinations, partial or total conserving of the original spelling, foreign plural or case forms or indeclinability.
Examples and related terms
A loanword is distinguished from a calque (or loan translation), which is a word or phrase whose meaning or idiom is adopted from another language by word-for-word translation into existing words or word-forming roots of the recipient language. Loanwords, in contrast, are translated.
Examples of loanwords in the English language include café (from French café, which means "coffee"), bazaar (from Persian bāzār, which means "market"), and kindergarten (from German Kindergarten, which literally means "children's garden"). The word calque is a loanword from the French noun calque ("tracing; imitation; close copy"); while the word loanword and the phrase loan translation are calques of the German nouns Lehnwort and Lehnübersetzung.
Loans of multi-word phrases, such as the English use of the French term déjà vu, are known as adoptions, adaptations, or lexical borrowings.
Although colloquial and informal register loanwords are typically spread by word-of-mouth, technical or academic loanwords tend to be first used in written language, often for scholarly, scientific, or literary purposes.
The terms substrate and superstrate are often used when two languages interact. However, the meaning of these terms is reasonably well-defined only in second language acquisition or language replacement events, when the native speakers of a certain source language (the substrate) are somehow compelled to abandon it for another target language (the superstrate).
Most of the technical vocabulary of classical music (such as concerto, allegro, tempo, aria, opera, and soprano) is borrowed from Italian, and that of ballet from French. Much of the terminology of the sport of fencing also comes from French. Many loanwords come from prepared food, drink, fruits, vegetables, seafood and more from languages around the world. In particular, many come from French cuisine (crêpe, Chantilly, crème brûlée), Italian (pasta, linguine, pizza, espresso), and Chinese (dim sum, chow mein, wonton).
Linguistic classification
Loanwords are adapted from one language to another in a variety of ways. The studies by Werner Betz (1971, 1901), Einar Haugen (1958, also 1956), and Uriel Weinreich (1963) are regarded as the classical theoretical works on loan influence. The basic theoretical statements all take Betz's nomenclature as their starting point. Duckworth (1977) enlarges Betz's scheme by the type "partial substitution" and supplements the system with English terms. A schematic illustration of these classifications is given below.
The phrase "foreign word" used in the image below is a mistranslation of the German Fremdwort, which refers to loanwords whose pronunciation, spelling, inflection or gender have not been adapted to the new language such that they no longer seem foreign. Such a separation of loanwords into two distinct categories is not used by linguists in English in talking about any language. Basing such a separation mainly on spelling is (or, in fact, was) not common except amongst German linguists, and only when talking about German and sometimes other languages that tend to adapt foreign spellings, which is rare in English unless the word has been widely used for a long time.
