Hesiod’s Theogony · C1
Greek roots in English (chaos, geo-, aether, hēmera, ouranos, hyper-, mnēmē, kyklos, gonia, chronos): C1 vocabulary building from the very first lines of the Theogony.

In the beginning, Chaos came to be. And then, everything else. Every name in this story is still hiding inside English words.

Then every line is a vocabulary lesson.
After Hesiod’s Theogony, lines 116–210
First came Chaos, a yawning gap; then Gaia, the Earth; misty Tartarus; and Eros, the most beautiful of the gods. From Chaos came Erebos and Night; from Night came Aether, the bright upper air, and Day.
Gaia bore Ouranos, the starry Sky, equal to herself; then the mountains and Pontos, the sea. With Ouranos she bore the Titans: Oceanus, Hyperion, Mnemosyne and the others, and last of all Kronos. Then the one-eyed Cyclopes and the three Hundred-Handers.
But Ouranos hid his children in the depths of the Earth, and Gaia groaned with pain.
First of all, Chaos came to be.
Names that became words

Chaos → chaotic. Gē → geology. Ouranos → Uranus. Easy!

Yes. Many English words are built from Greek roots: geo- (earth), -logy (study), hyper- (over), chrono- (time), cyclo- (circle). Knowing the root helps you guess new words.
Look-alikes and traps

Chronos, time, and Kronos, the Titan, are different! And sickle isn’t from kyklos.

Exactly. Similar-looking words can have different roots: ethereal (aether) vs eternal (Latin), mnemonic vs monogram. Check before you guess.
Day and memory

Ephemeral hides hēmera, day. And mnemonic and amnesia both hide memory.

Good, Philo. ephemeral = lasting a day, very short-lived. mnemonic = a memory aid (silent m). cosmogony = a story of the origin of the world.
