Relating to the Caspian Sea or its region, as a geographic word association.
The entry explicitly defines this sense of the English geographic adjective and separately documents the modern given name. This is a surface word association, not a proven literal meaning or formation intended by every family. The name’s literary association is documented; no fictional character trait or ancient people’s identity is assigned to a child.
Modern English name use; the geographic word has Latin ancestry.
The exact English entry documents a modern male given name popularized by C. S. Lewis’s Chronicles of Narnia. Separately, it traces the English geographic word through Latin Caspius plus an English suffix. This distinguishes documented name use from the ancestry of a geographic word, rather than claiming a universal ancient personal-name derivation.
