If you want to know what a word means, all you have to do is look it up in the dictionary, right? Actually, it’s a little more complicated than that. This episode of Crash Course Linguistics is all about semantics, or the area of linguistics concerned with meaning. We’ll learn about different types of semantic relationships, and how different languages define these relationships, as well as different approaches to semantics. And we’ll discover that the humble definition may be more complicated than we think.
