It’s always good to discover a word for something you know about but have always had to describe in the past, for want of knowing its name.
While working on the third draft of The Wound of Words, I discovered the word girandole. A girandole is a sort of decorative multi-branched candleholding apparatus, frequently wall-mounted rather than ceiling mounted (as with chandeliers), and sometimes backed with mirror for extra light-shedding and sparkliness.
