Here's another GPT-4 transcript, inspired by https://www.ling.upenn.edu/~beatrice/110/docs/uncleftish_beh.... In this case, not only it had to use invented words, but it had to invent them itself first.

--- input ---

Tell me about the structure of the solar system.

I want you to only use English words of Germanic origin; avoid using words derived from Latin or Greek. If there's no alternative, make up a new word by calquing the original into Germanic roots.

The sunstead is the sun and all things that go around it. In the middle is the Sun, a big, hot ball of glowing gas. Around the Sun are eight big worldrocks. From nearest to farthest, they are:

Mirkworld - The nearest worldrock to the Sun, small and fast. Lovegoddessworld - The hottest worldrock, with thick air and no water. Earth - Our home, the only worldrock known to have life. Redworld - A red, rocky worldrock with thin air and high mounts. Greatthundergodworld - The biggest worldrock, with many fellowtravellers and a big red spot. Harvestgodworld - A gas worldrock with a thin ringstead around it. Skygodworld - An iceworldrock that lies on its side, with a thin ringstead. Seagodworld - The farthest iceworldrock, with strong winds and blue clouds.

Besides the worldrocks, there are smaller rockbits and icebits that also go around the Sun. The rockbits are mostly in the Rockbitbelt between the Redworld and Greatthundergodworld. The icebits come from the far edges of the sunstead, in the long way out Icyrockcloud and the faraway Cloud of All.

The sunstead has a flat shape, with most things going around the Sun on near level paths. The worldrocks go around the Sun in a way called nearround paths. The Sun's pull keeps everything in the sunstead together.

Beyond the worldrocks, rockbits, and icebits, the sunstead also has spacegrit, small bits of rock and metal that fly through space. When spacegrit enters Earth's air and burns up, it makes a lightstreak that we can see in the night sky. If a bit of spacegrit reaches Earth's ground, it is called a starstone.

The Sun, which makes up most of the sunstead's weight, sends out a flow of charged bits that spreads far into space. This solar wind forms a wide bubble, the Sunshield, that surrounds the sunstead and helps shield it from high-speed bits coming from outside.

The sunstead's workings are steered by the pull between the Sun and the things that go around it. The worldrocks and fellowtravellers tug on each other, leading to small changes in their paths over time. The Sun's pull is strongest near it, so worldrocks closer to the Sun go around faster than those farther out.

As the Sun ages, it will go through changes that will have big outcomes for the sunstead. In about 5 billion years, the Sun will bloat into a Red Greatstar, swallowing Mirkworld, Lovegoddessworld, and maybe even Earth. Afterward, the Sun will shed its outer layers and shrink into a White Dwarf, a small, hot, dim star.

Lastly, the sunstead is but one of many star systems in our Starset, the Milky Road. The Milky Road is a wide, spiraling set of billions of stars, gas, and dust, and it is just one of countless starsets that make up the great Allthing.
