large island west of Italy, Latin, from Greek Sardō, Sardōn; perhaps named for the local Iberian people who had settled there; the original form and meaning of the name is lost. A Punic (Phoenician) stelle from 7c. B.C.E. refers to it as Shardan.
The oblique cases in Greek are sometimes Sardonos, etc. Related: Sardinian, which in 19c. sometimes was shortened to Sard. The historical Kingdom of Sardinia was formed in 1720 from the island and parts of Piedmont and Savoy; it became the nucleus of the modern nation of Italy.
