The key assumption in this article is that morphopragmatic change can be seen in shifts in the pragmatic meaning of a morpheme. This paper deals primarily with how the suffix /-ǧi/ has changed from the profession suffix to the pejorative suffix in Egyptian Arabic. It investigates how a morphopragmatic process has proceeded from creating Nisba construction in Arabic to a pejorative suffix. Data are taken from words selected from the Internet Archive which include texts, TV news captions, radio transcripts and advanced web sites. The samples are Arabic words with the suffix /-ǧi/. The researcher purposively sampled 150 words out of 6594 Arabic words ending with the sounds [-ǧi]. A descriptive research design was adopted to analyze the qualitative data. Morphopragmatics, speech act theory, conventional implicature and politeness theory are used to justify the pragmatic meaning change of the suffix /-ǧi/ in some genuine Arabic words. The suffix is attached to Arabic words to create neologisms which carry pejorative meaning. The paper argues that the tendency to use the suffix to denote a profession has ceased to function in some words.
