How did the Greeks name the Gods and Goddess?

Ok, Zeus is the king, Hera is the queen, Poseidon is the ocean or basically water, Hades is death, Demeter is agriculture, Athena is smartness or wisdom, Hestia is hearth basically fire, Hephaestus is crafts, Hermes is the messenger of the gods, Apollo is sun and music, Artemis is moon and animals, and last but not least Aphrodite is beauty and love.

Aries is a God of War, bloodlust, violence, manly courage, and civil order. The son of Zeus and Hera, he was depicted as either a mature, bearded warrior dressed in battle arms, or a beardless youth with helm and spear. His attributes are golden armour and a bronze-tipped spear, and his sacred animals are the eagle, owl, the vulture and the venomous snake.

Dionysus or Διόνυσος in Greek - god of wine, parties and festivals, madness and pleasure. He was depicted in art as either an older bearded god or a pretty effeminate, long-haired youth. His attributes include the Thyrsus (a pinecone-tipped staff), drinking cup, grape vine and a crown. A later addition to the Olympians, in some accounts he replaced Hestia

The Titains are still technically gods so I should tell you about some of them.

Lêtô or Λελαντος in Greek was the goddess of motherhood, mother of Artemis and Apollo.

Ouranos or Ουρανός in Greek was god of the heavens and father of the Titans

Krónos or Κρόνος in Greek was the leader and the youngest of the first generation of divine descendants of Gaia, the earth, and Uranus, the sky. He overthrew his father and ruled during the mythological Golden Age, until he was overthrown by his own sons, Zeus, Hades, and Poseidon and imprisoned in Tartarus.

Kronus was usually depicted with a Sickle, which was also the weapon he used to castrate and depose Uranus, his father.
