What is wrong with run- on sentences?

Run-on sentences occur when two or more independent clauses are improperly joined without appropriate punctuation or conjunctions, leading to confusion and a lack of clarity. They can make writing difficult to read and understand, as the reader struggles to identify where one thought ends and another begins. Additionally, run-on sentences can dilute the impact of the ideas being expressed, making the writing less effective. Proper punctuation enhances clarity and helps convey the intended message more clearly.
