External features refer to the physical characteristics and appearance of an individual or object that can be seen from the outside. These features can include a person's facial features, hair, body shape and size, and clothing, as well as the physical characteristics of an object, such as its size, shape, and color.
In the case of a person, external features can be used to identify and distinguish individuals from one another. For example, a person's facial features, such as their nose, eyes, and mouth, are unique to that individual and can be used to identify them. Similarly, a person's hair color, style, and length can also be used to differentiate them from others.
External features can also provide information about an individual's age, gender, and cultural or ethnic background. For example, certain hairstyles, clothing, and body adornments may be indicative of a person's age, gender, or cultural identity.
In the case of an object, external features can be used to identify and distinguish it from other objects. For example, the size, shape, and color of a car can be used to identify it as a particular make and model. Similarly, the size and shape of a smartphone can be used to distinguish it from other types of electronic devices.
External features can also be used to convey information about the function or purpose of an object. For example, the shape of a tool, such as a hammer or screwdriver, can indicate its intended use. Similarly, the shape and size of a piece of furniture, such as a chair or table, can provide information about its intended use and the space it is intended to occupy.
In conclusion, external features are the physical characteristics and appearance of an individual or object that can be seen from the outside. These features can be used to identify and distinguish individuals and objects from one another, as well as to convey information about their age, gender, cultural identity, function, and purpose.
