Here's a breakdown:
* Dictionaries aim for accuracy: Dictionaries are created by lexicographers who strive to be as accurate as possible in their definitions and usage examples. They use a combination of research, linguistic analysis, and expert consultations to ensure their entries are reliable.
* But, language is always evolving: Language is constantly changing, and new words, slang, and meanings appear all the time. This means that dictionaries are never completely static. They get updated regularly to reflect these changes.
* Different dictionaries, different approaches: Different dictionaries may have different focuses, target audiences, and approaches to defining words. Some are more prescriptive (telling you how words *should* be used), while others are more descriptive (reflecting how words are actually used).
* Subjectivity in language: Even with the best intentions, there can be some subjectivity in how words are defined. For example, the meaning of a word can depend on the context in which it is used, and different people may have slightly different interpretations.
So, the answer is:
Dictionaries strive to be accurate, but they are not infallible. They are snapshots of language at a particular point in time, and their definitions can be influenced by the lexicographer's perspective and the evolution of language.
Think of it this way: a dictionary is a guide, a tool, and a reflection of how we use language. It's not a perfect or unchanging source of truth, but it can be incredibly helpful in understanding and using words effectively.
