unsinkable
Can't go down
Unsinkable describes something that cannot be sunk, most often ships: The Titanic was famously called unsinkable.
The word appears more frequently in figurative contexts—an unsinkable spirit, an unsinkable optimist—suggesting resilience that persists despite setbacks.
The Titanic's fate has made the literal sense slightly ironic.
