Semantics is the study of meaning in language. It explores how words, phrases, and sentences convey ideas and emotions. For example, the word dog can refer to a specific animal, but it can also evoke feelings of companionship or loyalty. Understanding semantics helps us grasp the nuances of communication and how context can change meaning. In addition to words, semantics also examines how different languages express similar concepts. For instance, the Spanish word "perro" means the same as "dog" in English, but cultural differences can influence how these animals are perceived. This makes semantics essential for effective communication across diverse languages and cultures.
