Where you find all definitions, in a dictionary.
Dictionary meanings are usually accurate representations of the definitions of words as commonly understood in language. However, language is constantly evolving, so some definitions may be subject to interpretation or change over time. It's important to be aware of context and potential nuances in how words are used.
No, dictionaries contain a mixture of factual information (definitions, spellings, etc.) and subjective elements (such as example sentences, usage notes). They aim to provide accurate and authoritative definitions and interpretations of words, but they can also reflect language as it is commonly used, which may include slang, informal terms, or regional variations.
You can access Google's online web application which allows you to directly access Google's online dictionary and find the definitions of all words in the dictionary.

So you can't photocopy the dictionary, but you could (in theory) transcribe the factual information, none of which is covered by copyright (in the USA).
