Hi Nonparei
Subjective and objective it is
All words require bodies/brains to be of the class of signs. A sign is a triad, it requires that it is about something and it is a "placeholder" for the process in the given brain. I.e. the letter A is a placeholder for the process in the brain and it is a sign itself, which is about something. What a sign can be about can be objective or subjective.
So in the absurd sense no words can be objective as not requiring brains, i.e. not words are independent of brains. All understanding of all words requires brains and the reason we can understand each other is because we can think alike. The structure in your brain if so is similar enough to other humans that we can understand each other, but that understanding is inter-subjective. It requires 2 or more subjects with a certain level of cognition and similar culture/language. That connects to such words as research, repeat and replicate and there are 3 words in play - subjective, inter-subjective and objective
Now for the words objective and subjective they cover different similar meanings, but there is a problem involved.
First a simple subject - object relationship. In short it has to do with cause and effect; i.e. you can't change how an object is by changing how you think. Your thinking can't cause a change in an object and words are not magical. "I command by the magical nature of words this apple, which is now red to become green" won't work, where as words can sometimes work in such a way in a subject - subject relation. "Be a dear and fetch me a cup of coffee". So a subject(s) -subject(s) relationship is in part inter-subjective, because it takes place between 2 or more subjects. I.e. humans and other relevant life forms, for which you have to look at them as individuals in part.
Now an object - subject relationship can make sense as how physical processes can influence the human world, where as an object - object relationship is universal so for all humans and involve physical processes, which are in the strong sense independent of all brains, when it comes to in part causation.
Now yesterday I read a book, which translates to the following title: Theories of science as relevant to practitioners within pedagogy.
In other words for the idea that you can explain everything based on observation(seeing through your eyes objects) and then test it, it breaks down for those of us, who work with humans as humans in toto, because we need to use all 3 kinds of science; natural, social and humane. We need to use several methodologies and be able to differentiate between based on evidence versus informed by evidence.
Now what goes on in a given brain is for some processes not objective, because as physical process they are what makes the thing - Homo Sapiens Sapiens - a subject and I can't help that you within natural science can't differentiate between subject and object across different methodologies, because you want to have the only methodology, so you can in effect try to control other humans, because only you understand truth.
