Yes, a language is a library of small ideas that can be joined to make larger, more complex ideas, which will be internally consisent to those native to it. Everything is ultimately just information. This can go off on all sorts of tangents.
WRT science, which is probably what's irritating you, words that are keywords in science have a meaning that has been defined by consensus within a given discipline, and one is not allowed to change those meanings because it creates confusion. If one wishes to present a new idea/phenonmena, it has to be done using words that are not already taken.
