A coherent paragraph flows smoothly because each sentence is connected to others by patterns in the language such as repetition and transitions.
Step-by-step explanation:
Coherency is the most important and key feature that makes a paragraph beautiful and noteworthy. Coherence is a characteristic that joins words and sentences and brings them together to form one logical piece of writing.
Coherent paragraphs are those that have a smooth flow of ideas and notions and the readers can find a consistency and logical pattern of ideas.
Coherency maintains a transition of concepts and creates a relevancy of ideas coming one after the other in an ordered and appropriate sequence. Therefore a coherent paragraph will always flow smoothly.
