The term "slice" can have several different meanings depending on its context.
In a general sense, it refers to a piece or portion of something, often used in reference to food such as bread, pizza, or cake. For example, you might ask for a slice of pie or expect your server to cut the sandwich into slices before serving it.
In addition, "slice" can also refer to a specific type of cutting tool that is used to make thin pieces of something, such as bread or vegetables. This tool typically has a sharp blade on one side and a flat surface on the other for spreading or scraping off excess material.
Finally, in some contexts "slice" can also refer to a specific type of shot in sports like tennis, golf, or pool where the ball is hit with an angle or spin that causes it to move through the air in a curved path. This type of shot is often used to get around obstacles or reach difficult areas of the court/green/table.
