seaworthy

the compound adjective 'seaworthy' is a transparent formation from two old english roots. the first element, 'sea', descends from proto-germanic saiwiz, which referred to a large inland body of water or the sea itself. the second element, 'worthy', originates from proto-germanic werþaz, meaning 'value' or 'worth', combined with an adjectival suffix. the literal combination, 'sea-worthy', thus means 'fit for the sea' or 'of sufficient worth/quality to face the sea'. this term emerged in the late 16th century within the context of maritime commerce and naval affairs, specifically describing vessels deemed adequately constructed, equipped, and maintained to withstand the perils of sea voyages. its figurative use, implying general readiness or fitness, developed later by analogy.

Structure: sea (body of salt water) + worthy (deserving or fit for) sea: from old english 'sǣ', of germanic origin; related to dutch 'zee' and german 'see'. functions as a noun root denoting the large body of salt water. worthy: from old english 'wurþig', from 'weorþ' (worth) + '-ig' (adjective-forming suffix). functions as an adjective-forming suffix meaning 'deserving of, fit for, or suitable for'.
