In English, the phrase "features and characteristics" is often used.
However, I, as a non-native English speaker, can't understand the difference between them.
Longman Dictionary of Contemporary English says:
feature: a part of something that you notice because it seems important, interesting, or typical
characteristic: a quality or feature of something or someone that is typical of them and easy to recognize
As the definition of "characteristic" shows, the word "characteristic" entails "feature".
In spite of this fact, you don't use either of them, but you often use the two words at the same time. Why?
Also, when you say "human features and characteristics", does "features" mean "someone's face" and "characteristics" mean "character"?
