Caviare (3 syl.).
Caviare to the general. Above the taste or comprehension of ordinary people. Caviare is a kind of pickle made from the roe of sturgeons, much esteemed in Muscovy. It is a dish for the great, but beyond the reach of the general public. (Hamlet, ii. 2.)
All popular talk about lacustrine villages and flint implements is caviare to the multitude.Pall Mall Gazette,
