If you can not define what a word means, then the word ends up meaning different things to different people and thus not only creates conflict and confusion, but also relays error to the young and leads to the aging and decay of a society.
Using words without definition is subtle deception in action. There is no word in any language that truly has no definition. The concept that a word represents might be difficult to explain, but if the word had no concept associated with it, then it wouldn't really be a word.

What makes you think that a property can be defined, which is to say, without leading to an infinite regress of definitions?
Definitions only need to be stated when there is potential question involved. If you examine a more precise definition for the word "property", then you should see why I asked the question. It should be a short discussion.
Eudaimonist said:
I will loosely describe a property as anything that is true of an entity. To speak of a property is to have a concept about an entity that we form by isolating some feature of the entity for consideration. The referent of the concept is some limited, identifiable aspect of the entity. This may not really be a definition, but I think it's as close as we can get to one.
In this part, you basically have said that the word "property" means "a true feature or aspect of an entity".
The substitution of one word for another is not really a definition, as you pointed out. In this the word property is substituted by the words "aspect" and "feature".
A definition requires that a concept be related to something outside that concept so as to be able to identify it from other concept relations. If you were to define an apple, then you would need to relate it to concepts that narrow down all possibilities of it being anything other than the concept you had in mind.
You could not say that an "apple is a fruit" as a complete definition because there are other fruits.
You could not say that an "apple is red" because other things are red and every apple isn't actually red.
You could not say that an "apple has seeds" because many things have seeds.
Think of all of the debates and discussion you have been involved in that use the word "God" yet the only definitions for the word are merely limited features and not a real definition, i.e. "God is the creator", "God is omniscient", "God is all mighty"....
None of these types of descriptors actually define God but merely tell of a few aspects.
The real question would be, "What makes something a God as opposed to being anything else?"
What makes an apple what it is as opposed to being anything else? Words such as "apple" can be difficult to define in a meaningful way simply because the most meaningful aspect of the apple involves direct experience of taste. We don't define our taste senses very well and thus when those sense are involved, we can't relate in words exactly what we intend. It is the lack of good definitions of taste that prevent us from being able to use words to communicate tastes.
What makes a property what it is as opposed to being anything else? Most people have not looked at the word's definition simply because it tends to be sufficiently gathered from a young age without anyone ever really explaining it.
I beleive that you will find that if you try to actually define what a property really is, then you will see that it is something that must indeed have affect on something so as to gain that property and how it affects other things is what categorizes which kind of property is involved. The degree of affect also comes into something's properties.
You can not have a property without relative measurement of affect. Something has the property of solidity only if it is substantially more solid than a standard. Something has the property of large size only if it is larger than a standard. You can not have a property without something else to compare it to. When comparing it, you are examining the differences in potential affect.
If you look at the OP and replace the word "affect" with the word "properties", it will end up saying exactly the same thing. I used the word "affect" simply because it helps point out that there must be something else involved.
When Aristotle spoke of existence, he never mentioned the fact that all properties are relative. The word "affect" used in the OP helps to relate the aspect of relativity in existence. In fact, without that aspect of relativeness, the universe itself could never happen and would not exist at all.
Make no mistake, I have extreme respect for Aristotle. He was WAY above those around him at the time. But we have a 2300 year advantage. We don't have to be as great as he just to add a little on to what he could so clearly see and document so very long ago.
Aristotle could see in his mind very many relationships in reality that far exceeded the typical for his day. But today, we can go far beyond that. We can see in our minds how the universe ever began from the start and where everything he was seeing came from and how it all relates.
There is nothing that Aristotle saw that we cannot see even better now and with far more detail. But notice how often he was trying to define words and concepts merely so he could discuss anything else. Just like anything else, if you want to know how the universe came about, you must first get some concepts and definitions straight. The presumption that everyone has the same understanding of words and their relation to other words is what is keeping people from avoiding irrationality.
