Scullery \Scul"ler*y\, n.; pl. Sculleries. [Probably originally, a place for washing dishes, and for swillery, fr. OE. swilen to wash, AS. swilian (see Swill to wash, to drink), but influenced either by Icel. skola, skyla, Dan. skylle, or by OF. escuelier a place for keeping dishes, fr. escuele a dish, F. ['e]cuelle, fr. L. scutella a salver, waiter (cf. Scuttle a basket); or perhaps the English word is immediately from the OF. escuelier; cf. OE. squyllare a dishwasher.]

1. A place where dishes, kettles, and culinary utensils, are cleaned and kept; also, a room attached to the kitchen, where the coarse work is done; a back kitchen.

2. Hence, refuse; filth; offal. [Obs.]

--Gauden.
