Conventional implicature refers to the meaning that is implied by a word or phrase in a specific context, rather than being part of the literal meaning. This type of implicature is tied to the conventional use of language, where certain expressions carry additional meanings that are understood by speakers of the language. For example, when someone says, "She is rich, but she is not happy," the word "but" implies a contrast between wealth and happiness. Unlike other forms of implicature, conventional implicature does not rely on the context of the conversation or the intentions of the speaker. Instead, it is based on the established meanings of words and phrases within a language. This makes it predictable and consistent across different situations. Understanding conventional implicature is important for effective communication, as it helps listeners grasp the nuances of what is being conveyed.
