> As we have all come to understand in recent years, CHAIRS can HAVE WHEEL, but CHAIRS can also HAVE LEGS . They can have a BACK, or they can lack them. They can be WELL BUILT or they can be WEAK . They can be strong or they can be weak. They can be short or they can be tall. What does the word CHAIR mean? It seems like a word that doesn't mean anything at all?

You sit on it (butt don't take it with you).

Next question, please.

Sitting on an immovable object doesn't turn it into a chair, like sitting on the ground.

[hypertele-Xii]

Just because you don't take it with you doesn't mean it's immovable.

Though you could start calling a particularily comfortable spot "yours to sit on", a kind of proto-chair, perhaps even a throne.

So a horse is now a chair? I sit on it but I don’t take it with me. I can’t lift a horse, after all.

[hypertele-Xii]

You don't have to lift a horse to take it with you, they move on their own (that's what makes them so useful), are domesticated and will follow you when properly handled.

Also, humans have been putting a type of chair on horses for some 2700 years, called a saddle, and sitting on that.
