What isn’t a social construct?
even numbers may be social constructs.
MEST (matter, energy, space and time) may be infinitely divisible, it may not be made up of units.
And units of measure, such as inches and feet, are definitely social constructs.
Not only that, but no two meter sticks have ever shared the exact same length.
If you looked at the ends of any two meter sticks under a microscope, you’d find one is a little longer than the other.
So our units of measure are always changing.
But what constitutes a little, or slight deviation, is relative to the collective/individual minds of the species apprehending it.
eventually, after 1000s or 1000000s of years, meter sticks may evolve into something a lot longer or shorter than the meter sticks of today.
Same with words, no people or person has ever uttered the same word the exact same way twice.
each time you say the word: change, it’ll sound a bit different.
This difference may or may not be perceptible to you and other listeners, but it’s there.
And furthermore, you’ve never meant the exact same thing by a word either.
Your idea of a dog is always changing.
When you think about what a dog is, different thoughts, feelings, images and sounds spring to mind/the same thoughts, feelings, images and sounds spring to mind differently.
So language, both in sound and in meaning is continuously mutating.
This is how language evolves into different languages after centuries or millennia.
An accumulation of imperceptible changes in sound and meaning over short periods of time, giving way to perceptible changes over long periods of time.
The English of 3019 would probably be largely incomprehensible to the English of 2019, just as the English of 1019 is largely incomprehensible to the English of 2019, unless we use computers to keep track of sounds and meaning, but even then, computers are always changing, their recording of sounds are imperfect, and they can’t really record meaning, they can record definitions, but the meanings of definitions are entirely in our heads, so using computers to keep track of language will only slow the process of linguistic change down, delay the inevitable, not stop it.
