What are Two or more sentences written as if they were one sentence without proper punctuation?

Two or more sentences written as if they were one sentence without proper punctuation create a run-on sentence that can confuse readers by blending distinct ideas together without clear separation. For example "I love to read it helps me relax" combines two thoughts but lacks the necessary punctuation to clarify the relationship between them. Such constructions can hinder comprehension and make writing less effective. Proper punctuation is essential for clear communication.
