What serious errors can occur when someone writes the way they speak?

Writing the way someone speaks often leads to fragments and run-on sentences, which significantly disrupt the clarity and flow of the writing. When speaking, individuals tend to use natural pauses and verbal cues that do not directly translate into written form. For instance, sentences that are clear and understandable when spoken may lack the necessary grammatical structure when written, resulting in fragments—pieces of sentences that do not express a complete thought. Additionally, the spontaneity of speech can lead to run-on sentences, where multiple ideas are improperly connected without appropriate punctuation or conjunctions. This lack of formal structure can confuse the reader and obscure the writer's intended message. Understanding these issues highlights why it's crucial for individuals to adapt their writing style for clarity and correctness, as written communication requires more precision and formal structure than verbal communication typically allows.
