Etymology
the word 'seaworthiness' is a modern english compound formed from three native english elements. its core, 'worthy', originates from the old english 'wurþig', meaning valuable or deserving, which itself derives from the proto-germanic 'werþaz' (value, worth), traceable to the proto-indo-European root 'wert-' (to turn, to wind). the prefix 'sea' specifies the domain of fitness, while the suffix '-ness' nominalizes the adjective 'seaworthy' into an abstract state. thus, the literal progression from 'value' and 'fitness for the sea' to the modern legal and maritime term for a vessel's condition of being adequately prepared and safe for ocean travel is clearly logical.
