Any language is necessarily a finite system applied with different degrees of creativity to an infinite variety of situations, and most of the words and phrases we use are "prefabricated" in the sense that we don't coin new ones every time we speak.
David LodgewhhheeeEEEEEEEEEEEEEEE! The scream of jet engines rises to a crescendo on the runways of the world. Every second, somewhere or other, a plane touches down, with a puff of smoke from scorched tyre rubber, or rises in the air, leaving a smear of black fumes dissolving in its wake. From space, the earth might look to a fanciful eye like a huge carousel, with planes instead of horses spinning round its circumference, up and down, up and down. Whhheeeeeeeeeee!
