Thus, after the eradication of Latin and Greek derivatives:
"For most of its being, mankind did not know what things are made of, but could only guess. With the growth of worldken, we began to learn, and today we have a beholding of stuff and work that watching bears out, both in the workstead and in daily life.
The underlying kinds of stuff are the firststuffs, which link together in sundry ways to give rise to the rest. Formerly we knew of ninety-two firststuffs, from waterstuff, the lightest and barest, to ymirstuff, the heaviest. Now we have made more, such as aegirstuff and helstuff.
The firststuffs have their being as motes called unclefts. These are mighty small: one seedweight of waterstuff holds a tale of them like unto two followed by twenty-two naughts. Most unclefts link together to make what are called bulkbits. Thus, the waterstuff bulkbit bestands of two waterstuff unclefts, the sourstuff bulkbit of two sourstuff unclefts, and so on. (Some kinds, such as sunstuff, keep alone; others, such as iron cling together in chills when in the fast standing; and there are yet more yokeways.) When unlike unclefts link in a bulkbit, they make bindings. Thus, water is a binding of two waterstuff unclefts with one sourstuff uncleft, while a bulkbit of one of the forestuffs making up flesh may have a thousand or more unclefts of these two firststuffs together with coalstuff and chokestuff.
At first it was thought that the uncleft was a hard thing that could be split no further; hence the name. Now we know it is made up of lesser motes. There is a heavy kernel with a forward bernstonish lading, and around it one or more light motes with backward ladings. The least uncleft is that of everyday waterstuff. Its kernel is a lone forwardladen mote called a firstbit. Outside it is a backwardladen mote called a bernstonebit. The firstbit has a heaviness about 1840-fold that of the bernstonebit. Early worldken folk thought berstonebits swing around the kernel like the Earth around the Sun, but now we understand they are more like waves or clouds."
