Arablish
Arablish, a portmanteau combining the words Arabic and English, is a slang term for the phenomenon of code-switching between the two languages and/or macaronically using features of one in the other. It is alternatively termed Arbalizi, a portmanteau combining the words Arabic and Inglizi (the word for 'English' in Arabic).
Usage of Arablish/Arbalizi particularly among the youth may be as a result of poor knowledge of one language or the other or both, or may be usage for introducing a humorous effect. Arablish/Arablizi is being increasingly used in ordinary conversations and online.[1]
Arablish usually consists of either filling in gaps in one's knowledge of Arabic with English words, speaking Arabic in such a manner that (although ostensibly "Arabic") would be incomprehensible to an Arab language speaker who does not also have a working knowledge of English.
