Rapid advances in information technology and proliferation of social media services have caused a radical transformation of human communication. Having created a social media presence people engage in computer-mediated communication, set their own goals as well as perfect their knowledge of English as a global language. The richness and diversity of computer-mediated discourse is concentrated in multiple online experiences and therefore enables to study a great number of linguistic changes. Various studies of computer-mediated discourse analyze socio-psychological characteristics in coherent sequences of sentences, propositions, speech or turns-at-talk. The given article aims at presenting vocabulary teaching strategies to new computer-mediated language and their influence on students' acquisition. Our contribution provides an overview of the recent new entries of computer-mediated vocabulary in online crowdsourced dictionaries. The main ways of forming new words as well as wide-spread semantic changes are viewed (acronyms, compounds, suffixes, blended words, conversion, etc.) Computer-mediated vocabulary teaching in the classroom covers change, diversity, disputes in economical, political, social spheres (such as narcissistic tendencies, emotional correctness, excessive use of social media and increasing reliance on technology, equal rights movement, task-based employment, etc). As the social media universe strives for a thorough integration with the user's life language learners are expected to embrace the latest changes in linguistic norms and devise an appropriate philosophy of language management.
