'seabird-like' originates from the combination of 'seabird' and the suffix '-like', where 'seabird' refers to birds that live near the sea, and '-like' means 'resembling or similar to'.

The term 'seabird-like' evolved from the combination of 'seabird', a term used since the 19th century, and the suffix '-like', which has been used in English since Old English times to denote similarity.

Initially, it meant 'similar to a seabird', and this meaning has largely remained the same in modern usage.
