[ar-ee-veest; French a-ree-veest]
1. a person who has recently acquired unaccustomed status, wealth, or success, especially by dubious means and without earning concomitant esteem.
1900-1905; Arriviste comes from French, from arriver, “to arrive,” from (assumed) Vulgar Latin arripare, “to reach the shore,” from Latin ad-, “to, toward” + ripa, “shore.”
“He excavates enough dirt that, midway through the book, the reader loses sympathy with Bernays, who comes across as an insufferable egotist and insecure, name-dropping arriviste.”
