Just my thoughts...I believe our mind is pre-programed....and outside influences what we use or don't use.....so round is round to everyone, jagged is jagged to everyone, smooth is smooth to everyone etc etc....

So use is the determining factor and not shared knowledge. Shared knowledge is the result of intermingling...not the catalyst for ideas.

I remember being taught in elementary school about the different shapes. Later, in junior high (they’re back to using that term now!) in geometry, shapes became a little more complex.

I do agree with your idea about usage versus shared knowledge, though. I hadn’t given that much thought, but it makes perfect sense.
