Etymology: "Linearis" is the Latin source of the English "linear," and it is formed from "linea," meaning "line," which itself comes from "linum," the word for flax. The connection runs through the thread: flax fibres were spun into linen thread, and a taut thread or cord was the everyday image of a straight line. Latin "linea" came to mean a line in the drawing and measuring sense, and "linearis" was built on it to mean "of or pertaining to a line" or "arranged in lines." English took "linear" directly from Latin in the 17th century, when mathematicians and natural philosophers needed precise vocabulary for straight-line relationships. Its mathematical use, where a linear equation has variables appearing only to the first power and so graphs as a straight line, developed from that original geometric sense. The word still carries the flax-thread picture inside it.
