Hi Leticia, the terms "spot" and "fleck" are both used to describe small marks or dots, but there are some slight differences between them. Spot: A spot generally refers to a small round or circular mark that stands out or contrasts with its surroundings. It can be a different color, shape, or texture than the surrounding area. Spots are often more defined and noticeable. For example, you might refer to a spot on a ladybug's back or a spot on a leopard's fur. Fleck: A fleck, on the other hand, refers to a small speck or patch of color or material that is typically irregular in shape. Flecks are often smaller and more scattered than spots. They can be tiny particles or fragments dispersed within a larger surface. For instance, you might describe the flecks of color in a painting or the flecks of glitter on a craft project. In summary, spots are usually more distinct and defined, while flecks are smaller and scattered irregularly. Both terms are used to describe small marks, but the choice between them depends on the specific characteristics and context of the mark being referred to. The picture below is a black and white marble with flecks of bright gold. I hope this clarifies the difference for you! If you have any more questions, feel free to ask. 😊👍
