Introduction

Code-switching is a linguistic phenomenon that occurs when speakers alternate between two or more languages or dialects within a single conversation. It is a common practice in multilingual communities where individuals are proficient in more than one language. The study of code-switching has gained significant attention in the field of sociolinguistics as researchers seek to understand the motivations and implications of this language behavior.
