Only if, and when, you human beings make them so.
Well obviously.
Why?
What would be the 'actual purpose' for doing this?
If it is to show and/or prove that words could be in a loop of 'almost' infinite definition, then I am pretty sure that this does not need actual proving here, as it is an already known Fact, by the readers here.
But, in saying this I could also point out and reveal that one could just define a word, by just 'looking in' a dictionary, and just define all of the words that were used to define that word, again by just 'looking in' the exact same dictionary, and then just keep doing the exact same thing here, until 'the dictionary' fulfils the 'almost' 'infinite definition loop', which was made up and created by human beings.
And, if there is 'not yet' 'a dictionary' nor 'a book of Life' in which every name, or word, within it provides a crystal clear big and full irrefutably Accurate picture of all-there-is, then you human beings, and 'your language', will just keep evolving, and changing, until 'that book' is written.
Which it obviously is HERE-NOW.
