This point was raised during a much larger philosophical discussion.
I took the line that the definition of a word is subjective, it exists within the mind of the user. The object it is describing is objective (naturally), the word itself is objective (so long as it is written down or remains as sound waves in the air), but what you take the word to mean is subjective. The fact that there are very common definitions is a result of linguistic communication and dictionaries but that does not mean that that is what you take a word to mean, the definition exists only in your mind. I thought that for a definition to be objective it would have to exist pre-human thought.
I am very new to philosophy and objectivism. I was looking for some input on the question and also my reasoning.
