c.1430, from L.
sardina, from Gk.
sardine, sardinos, often said to be from
Sardo "Sardinia" (see
Sardinia), the Mediterranean island, near which the fish were probably caught and from which they were exported. But cf. Klein: "It is hardly probable that the Greeks would have obtained fish from so far as Sardinia at a time relatively so early as that of Aristotle, from whom Athenaios quotes a passage in which the fish
sardinos is mentioned." Colloquial phrase
packed like sardines (in a tin) is recorded from 1911.
