    • n lubricant Any natural or artificial material that may be used to lubricate the rubbing surfaces of machinery, in order to lessen their friction upon each other. Natural non-volatile oils and greases are the typical lubricants; but the variety of materials and compounds used is very great, including some metallic alloys.
