Définition et Signification de "semantic shift"

What is "semantic shift"?

Semantic shift refers to the change in meaning of a word or phrase over time. This can involve a broadening of meaning, where a word takes on additional meanings, or a narrowing, where it loses some of its original meanings. For example, the word "mouse" originally referred only to the small rodent but has expanded to also mean a computer device. Semantic shift can occur due to cultural changes, technological advancements, or social influences. Understanding semantic shifts helps linguists trace how language evolves and reflects changes in society.
