To lubricate something is to make it easier to move, or to move against. For example: A door that is hard to open may h â¦ ave a hinge that is very tight. To lubricate the door you would add a type of grease or oil that is designed to make the hinge easier to move. In this case the grease or oil being used is a type of lubrication. Another example: Car engines require lubricants so that the rubbing of metal on metal does not cause engine failure. Cars are regularly serviced (oil changes, grease on ball bearings, etc) by adding lubricants to various parts of the engine to keep them running smoothly.
