What is saboteur? How to use in English

The word "saboteur" originates from the French language. In World War I, French workers in the factories producing war materials, particularly in the textiles and munitions industries, began intentionally damaging or destroying the equipment and products to disrupt the war effort. These actions were referred to as "saboter," which means "to break or destroy." The term referred to the practice of harming or obstructing the enemy's production capacity by creating chaos and disrupting the supply chain. The term was later adopted in English to describe those who engage in similar activities to hinder or disrupt an opponent's plans or operations. The term has since expanded to include any individual or group that intentionally damages or disrupts the normal functioning of an organization, facility, or system.
