"Usually it is uses of words, not words in themselves, that are properly called vague"

This quote by J. L. Austin is referring to the principle of ambiguity in language. He is recommending that it is not the words themselves that are unclear, however rather the method which they are used. This is because words can have numerous meanings and can be translated differently depending on the context. For instance, the word "huge" can suggest various things to various individuals. To one person, it might indicate large, while to another it might imply essential. Therefore, it is making uses of words that can be vague, not the words themselves. Austin is stressing the importance of context when utilizing language, as it can help to prevent misconceptions and confusion. He is also suggesting that it is necessary to be aware of the potential for uncertainty when utilizing language, as it can lead to misconceptions and miscommunications.
