on ecommerce sites, you may encounter one of two possible language-switching features: language switchers and country switchers.Examples of code-switching include: A Spanish and English speaker saying, "Pero WHY do I have to go a la casa?" Or, "But WHY do I have to go home?" A speaker of Black Vernacular English saying, "We finna get to school on time today," instead of "we are going to get to sign language alphabet school on time today." happens when someone begins speaking in a different language or dialect throughout the course of a conversation. This lexical practice occurs both by accident and on purpose for a host of different reasons.
