Scientists make up words to communicate economically. We could communicate with a vocabulary of no more than 5,000 words, but our sentences and paragraphs would be much longer.
Square, cube, pyramid, mathematicians just make up words to sound smart. Wouldn’t it be so much easier to say
“Four sided two-dimensional figure with all four sides and angles equal”,
“Solid consisting of six four sided two-dimensional figures with all four sides and angles equal, and with the vertex angles of the solid all equal as well.”
“A solid consisting of two dimensional figures with three sides each, plus another two dimensional figure dimensional figure with an arbitrary number of sides equal to the number of the other sides and sharing an edge with every one them, and a vertex angle including all the other figures...”
“Sentence”, “paragraph”, “verb”, “noun”. Grammarians just make up words just to sound smart.
Aaaaaamen!
