- A style of four-legged drop-leaf table in vogue in England, chiefly in the later Georgian period.
Sorry, no etymologies found.
Other details we can also imagine - the stiff-backed chairs with carpet-worked seats, the Pembroke table in the centre, like that upon which Mr. Woodhouse had always been accustomed to have his meals; the fireplace with hobs and high moulded chimney-piece, adorned with miniatures in black frames.
And Mrs. Sophie Velvet caused me another pang a second or two later because I saw she’d put her glass on the Sheraton Pembroke table and the glass foot was wet, silly cow.
