When it comes to writing, vocabulary is key. Using the same phrases and words repeatedly can sound boring and dull. That's why it's important to have a variety of synonyms for common phrases such as "flow of words". Some other words that can be used to describe the flow of words are "verbalization", "articulation", "expression", "communication", and "narration". Each of these words has a slightly different connotation and can add depth and complexity to a writer's work. By using a variety of synonyms, writers can keep their audience engaged and interested throughout their work.
