This paper reports and discusses the findings of an exploratory study on the influence of English vocabulary in the on-line environment of Pakistani adolescents. Some linguists, such as Sapir (1929) [1] and Whorf (1940, 1956) [2] have claimed a close link between culture and language, therefore, this study explores whether the study of a foreign language influences its use in an on-line environment, even when individuals are communicating in their first language.
