Whenever Asimov was stuck, he would make a play on meaning in his names:

Preem Palver => Prime (First) Palaver (Speaker).

Hari Seldon takes the name "Chetter Hummin" => Cheater Human.

Dors Venabili => Gift of the Venerable

Bel Riose is simply Belisarius.

Ebling Mis has bad health (it ebbs) and then he misses the right answer.
