A "prominent feature" refers to a noticeable or significant characteristic of an object, person, or place. It is something that stands out and can easily be identified or recognized. For example, the Eiffel Tower is a prominent feature of the Paris skyline due to its unique design and height. In the context of human appearance, a prominent feature might be a distinctive nose, large eyes, or a strong jawline. These features can define a person's look and contribute to their overall identity. Recognizing prominent features helps in understanding and describing both people and places effectively.
