This study is concerned with the English neologisms of Generation Z Language users (popularly called Gen-Z), whose linguistic norm is gaining entry into the English language used in social media, thus influencing the language of four generations which are categorised based on birth years and shared cultural experiences. The four generations include Generation X, Millennials, Generation Z and Generation Alpha, and these categories of people form a set of active users of English Language, especially on social media. This language norm makes a remarkable impression on the vocabulary of English with the existence of social media since there is often an explosion in the frequency with which speakers make use of such innovation or construction in the target language. What is unique about the neologisms of the Generation Z English users is first, the pace with which they are formed and used and second, the ease with which they gain traction among diverse users. Although this speed is an unusual feature of language change which its process is measured, it is imperative to note that language innovation is ceaseless and remorseless. Every language that is spoken continues to change, not just century by century, but day by day. The aim of this study is to examine the neologisms formed by Generation Z users of English and establish the morphosemantic features peculiar to the formation of those words. The objectives are to i. identify Gen-Z neologisms, ii. analyse the possible sources and morphological processes used in the formation, and iii. ascertain the relationship between the new words and the corresponding old words (if any). In this study, some of the neologisms formulated in the last 15 years were accessed, the sources and origins of the words were investigated and finally the morphological processes used to achieve the words and their attendant meanings as well were examined. This study acknowledges the existence of Generation Z who exhibit unique characteristics that distinguish them from other past generations. Their distinctiveness is a product of their childhood and life in the technological, culturally diverse, digitally connected and socially conscious world. Being the core of the active population in this age, they influence various aspects of the society from technology and media to business, fashion and learning which indeed cause fundamental changes in the present world and initiate future directions. The evident rapid and profound changes in the English lexis in the last few decades require systematic linguistic investigation.
