About Text Features
All the parts of a narrative or article that aren't the primary text body are referred to as text features. These characteristics can be advantageous if they are succinct, pertinent to the material, and understandable, or they can be detrimental if they are badly structured, just marginally pertinent to the topic, or overly wordy. The patterns and structures that the author(s) employed to compose the text are referred to as the text's organisation. A text that is well-organized helps the reader by placing information in predictable places.
