Abstract

THREE KEY CONCEPTS WILL MAKE UP THE PILLARS OF THIS PAPER: SECOND, FOREIGN AND HERITAGE LANGUAGES. WHENEVER APPROPRIATE “ADDITIONAL LANGUAGE” WILL BE USED AS AN UMBRELLA TERM. A STUDY OF THE DOMAINS OF LANGUAGE USE WILL BE APPLIED TO THESE THREE DIFFERENT SOCIOLINGUISTIC CONTEXTS. TO DATE, THERE ARE NOT MANY EMPIRICAL STUDIES ON THE DOMAINS OF LANGUAGE AND, MORE SPECIFICALLY, AMONG YOUNG LEARNERS IN DIFFERENT AREAL CONTEXTS, AS IT IS THE CASE OF THIS STUDY.
