Apostrophes misused can lead to confusion (e.g., it's vs. its).
Homophone confusion can affect clarity (e.g., there, their, they're).
Incorrect verb forms, such as "I seen" instead of "I saw," undermine credibility.
Sentence fragments and run-on sentences disrupt sentence integrity.

Proper placement of modifiers is necessary to avoid ambiguity, ensuring clarity in meaning (e.g., "She drove her kids to school almost every day" vs. "She almost drove her kids to school every day").
