What I got was : basically, 'titan' in the word titanic means gigantic. huge. titans in Greek mythology were strong, powerful, immortal, and god-like deities, and they were brought down by the Gods. That is the greek mythology that the word 'Titanic' is derived from.
What I would consider ironic and quite frankly, interesting, is the fact that the Titanic (ship) was large and strong—and it sunk, never to be seen ever again, it's glory reduced to nothingness. And the same goes for the titans : they were glorious, arrogant, and huge, and even then they were sunk, or rather, lowered by the Gods of Greek Mythology.
