clinquer

A rare, old-fashioned verb meaning to give off a thin, tinny jingling or glittering effect — it survives mainly as the root of the everyday adjective clinquant (flashy, gaudy, all that glitters). The verb itself is essentially obsolete in modern spoken French.

• De faux bijoux clinquaient à ses oreilles. — Cheap-looking jewelry glinted and jingled at her ears.
• On entendait les clés clinquer dans sa main. — You could hear the keys jingling faintly in his hand.
• Les breloques clinquaient légèrement à son poignet. — The charms jingled faintly on her wrist.

You'll almost never see the verb clinquer itself in modern French — it's the adjective clinquant that thrives, used for anything cheaply flashy or gaudy, from jewelry to marketing.
