seabird

the word "seabird" is a transparent compound formed from two ancient germanic roots. "sea" derives from the proto-germanic saiwiz, which referred to a large body of water, a concept traceable to proto-indo-European. "bird" originates from the old english 'bridd', initially meaning a young bird, which later generalized to denote any bird. the compound logically combines these elements to specify a class of birds whose habitat and sustenance are intrinsically linked to the marine environment, illustrating a straightforward descriptive naming pattern in english.

Structure: sea (body of salt water) + bird (feathered vertebrate) sea: from old english 'sǣ', meaning "sheet of water, sea, lake, pool". of germanic origin. bird: from old english 'bridd', meaning "young bird, chick". of germanic origin.
