👉 The term "extradialectal" is used in linguistics to describe a person who speaks more than one language at the same time. This phenomenon can occur due to various factors such as learning, brain damage, or even genetic predisposition. In other words, an individual might be able to speak multiple languages fluently but not simultaneously because they are using them for different purposes or tasks. For example, someone who speaks two languages in a day could be considered an extradialectal speaker.
