After being introduced to Micro Linguistics in their First and Second Years, EFL Third Year students at the University of Mentouri, Constantine, will discover another field which is Macro Linguistics that deals with the study of language in relation to other disciplines. Therefore, we aim through the present module at developing the learners' abilities to understand the principles and branches of Linguistics, focusing mainly on Sociolinguistics-the study of language in relation to society- and Psycholinguistics -the study of language in relation to the mind.
