This paper focuses on examining the differences between boredom as experienced in learning the L2 and the L3. Its first part provides a theoretical background including the definition, causes of boredom and an overview of research findings, whereas the second part approaches boredom from an empirical perspective and as such it is devoted to the discussion of the results obtained from a mixed methods study conducted by the present authors on four university students of English. The collected data enabled the authors to identify the factors responsible for experiencing boredom in these two distinct language learning contexts.
