In linguistics, an internationalism or international word is a loanword that occurs in several languages (that is, translingually) with the same or at least similar meaning and etymology. These words exist in "several different languages as a result of simultaneous or successive borrowings from the ultimate source" (I.V.Arnold). Pronunciation and orthography are similar so that the word is understandable between the different languages.
It is debated how many languages are required so that a word is an internationalism. Furthermore, the languages required can also depend on the specific target language at stake. For example, according to Ghil'ad Zuckermann, the most important languages that should include the same lexical item in order for it to qualify as an internationalism in Israeli are Yiddish, Polish, Russian, French, German and English.
The term is uncommon in English, although English has contributed a considerable number of words to world languages, e.g. the sport terms: football, baseball, cricket, and golf.
European internationalisms originate primarily from Latin or Greek, but from other languages as well. Many non-European words have also become international.
Internationalisms often spread together with the innovations they designate. Accordingly, there are semantic fields dominated by specific languages, e.g. the computing vocabulary which is mainly English with internationalisms such as computer, disk, and spam. New inventions, political institutions, foodstuffs, leisure activities, science, and technological advances have all generated new lexemes and continue to do so: bionics, cybernetics, gene, coffee, chocolate, etc..
