Yes, fallacies of definition are one of the primary reasons for misunderstanding, e.g. we both are using the same word, we both have an idea of what the word means and/or are using it in a specific way; however, we both think the word means something different, and we both assume the other person is using the word in the way we are. Piles of disagreements have been built on this one simple fallacy. https://en.wikipedia.org/wiki/Fallacies_of_definition https://en.wikipedia.org/wiki/Fallacies_of_definition That's one of the reasons why I like how Rich Hickey begins all of his talks with precise deconstructions of the definitions for the words that are integral to the theme of his talk, as he does in "Simple Made Easy": https://www.infoq.com/presentations/Simple-Made-Easy https://www.infoq.com/presentations/Simple-Made-Easy Once you establish a common understanding for the meaning of the words you are using, you have not only cleared up any potential misunderstandings, but you have also implicitly established points of agreement and have established a solid foundation to build on.
