Use a simple sentence if you want to express a single thought to emphasize and be too verbose. Trying to say too much in a single sentence can confuse your reader. However, avoid using too many consecutive simple phrases, as this can make your writing sound cut. This simple sentence has an independent clause that contains a subject, dog, and a predicate, barking and raising the cat. This predicate has two verbs, known as compound predicate: bark and heist. This composite verb should not be confused with a compound set. In the backyard and in the cat, there are preposition phrases. A single sentence contains a subject and a verb, and it can also have an object and modifiers. However, it contains only an independent clause.
A run-one sentence consists of two or more independent clauses (i.e. clauses that have not been conditioned by the use of a relative pronoun or a subordinative conjunction) that are linked without proper punctuation: the “run on” clauses – in confusion rather than clarity, such as cutting roads without a sign for yield or stop. Independent clauses can be “mergers” because in “It is almost five and a half hours that we cannot reach the city before nightfall,” in which case the two independent clauses (between “five” and “we”) could be separated from a single period [… Five. We…], a comma and a conjunction (… five, and us…), or a semicolon (… Five; us…). Independent clauses can only be adequately linked with a comma (the comma). James Joyce`s novel Ulysses uses the current of consciousness that takes the literary license by deliberately breaking this grammatical rule by using long sentences, without sentences, run-on, especially in the last chapter “Penelope”.
In general, run-one phrases occur when two or more independent clauses are attached without a coordination conjunction (i.e. for and again, or correctly) or correct punctuation (i.e. a semicolon, dash or period).    A game can be as short as four words – for example, I drive them, or I drive them, she goes away – because in these brief cases, there are two subjects that are associated with two intransitative verbs.
