grease: [13] Latin crassus meant ‘solid, thick, fat’, and hence ‘gross, stupid’ (English borrowed it in this latter metaphorical sense as crass [16], and it is also the source of French gras ‘fat’). On it was based the Vulgar Latin derived noun *crassia ‘(melted) animal fat’, which passed into English via Old French craisse, later graisse, and Anglo-Norman gresse or grece. Old French craisse was the source of craisset ‘oil lamp’, from which English got cresset [14].
