Clevette appears to be a modern surname-style or place-style formation with a French diminutive ending. It does not point to a single long-established tradition so much as to a contemporary taste for names that sound European, compact, and slightly tailored.
That gives Clevette a polished and uncommon feel. The -ette ending softens the name, while the opening sounds make it feel crisp and distinctive. It has the atmosphere of something invented with care: not heavily historical, but not flimsy either. Clevette sounds refined, modern, and just unusual enough to stand apart.
