Language change refers to the natural evolution of a language over time. This can happen due to various factors, such as cultural shifts, technological advancements, and contact with other languages. For example, the rise of the internet has introduced new vocabulary and phrases, like emoji and hashtag, which were not part of everyday language a few decades ago. Another aspect of language change is the way pronunciation and grammar can shift. For instance, the English spoken today is quite different from that of Shakespeare's time. Words may take on new meanings, and some may even fall out of use entirely, reflecting the dynamic nature of human communication.
