Antifriction refers to reducing or eliminating the friction between two surfaces or materials. There are several synonyms that can be used to describe this process. One such word is lubrication, which refers to the use of a substance that reduces friction between two surfaces. Another term is slipperiness, which refers to the quality of being smooth and slippery, therefore reducing friction. Additional synonyms include sleekness, polish, and greasiness, which all describe a surface that allows for easy movement and reduces friction. Ultimately, the goal of antifriction is to reduce wear and tear on materials and to create a smoother, more efficient operation, which can be achieved through the use of these various synonyms.
