A speculative look at the names of some of the Titans.
Maia mother of Hermes.
Possibly a local Arcadian form of the great mother goddess as her name has several meanings, mother, midwife, good mother, dame, lady,
Themis T aspirated emis possibly connected to the verb Titheemi?
Iapetus the only similar greek word is the Verb Iaptoo
Leto is Leetoo in Attic Ionic but Laatoo in Doric.
Graves links this toa Semitic goddess but another overlooked possiblity is the obscure verb law meaning Watch. Leto as the goddess who watches?
Koios The Ionic dialect has a verb Koeoo that has the same meaning as Noeoo so Koios may have been the Mindful One?
His Consort Phoibee Yes its aspirate p in greek not Fibee! The radiant one.
Hyperion father of the Sun Moon and Dawn Overlord ?
Kreios Kreion Lord master
Names have meanings but the meanings of these names predate the Olympian gods and it may well that given how words can change of the centuries that the names meant something different thousands of years ago.
Probably about 3500 years ago or older since some people think the myths about Battle of the Titans or the gods fleeing Typhon reflect dim memories of the eruption of Thera? Did religion in Greece change after Thera's eruption?
Something to to think about and google the concept of earthstorms?
