dreadnought (n.)

literally (one who or that which) "fears nothing," from the verbal phrase (drede ich nawiht is attested from c. 1200); see dread (v.) + nought (n.). As a synonym for "battleship" (1916) it is from a specific ship's name.

The end for others sought,
Watch sloth and heathen Folly
Bring all your hopes to nought.
