The Internet has greatly influenced the daily lives of a large number of people. From the way people think, the way they present themselves, to the use of free time, the Internet has reshaped reality. It has also opened some new viewpoints when it comes to human interaction and communication. The aim of this thesis is to explore the influence of age on idiolects within the context of electronic communication. By examining the relationship between individual language use (idiolects) and age, the study shows how generational differences manifest in digital communication. In order to present the subject, the research is divided into three main sections. The first part focuses on the concept of idiolects, covering its etymology, and also the impact of age on personal language variations. The second section provides a comprehensive overview of electronic communication, including the history of the Internet, the rise of wireless communication, and the emergence of Internet language called Netspeak. The final section presents a survey analysing text messaging behaviours across different age groups, highlighting significant differences and similarities in language use and communication styles. The results suggest that age does influence idiolects in electronic communication, with younger and older generations showing different linguistic patterns. This research contributes to the understanding of how digital communication continues to evolve and reflects broader sociolinguistic trends.
