一個 Run-on Sentence 至少包含兩個獨立子句 (independent clauses)，但它們沒有被適當地連接起來。在此，我們亦對兩個獨立子句之間的標點符號作一說明。
我們必須瞭解的一點是，句子的長短實際上與句子是否 run-on 無關；run-on
The sun is high, put on some sun-block.
當兩個獨立子句僅用一個逗點來連接時，它們就構成所謂 comma-splice or
comma fault (用逗點分開兩個對等子句的錯誤) 的 run-on sentence。上面的例子就是
and, but, for, nor, yet, or, so 等連接詞。
The sun is high, so put on some sun-screen.
|3.||run-on sentences 通常發生在下列情況下：|
This next chapter has a lot of difficult information in it, you should start studying right away.
我們可以將這個句子中的逗點改為句點 (‧ period) 然後開始一個新的句子或改為分號 (；semicolon)。
however, moreover, nevertheless 等連接副詞 (conjunctive adverbs) 來連接時：
Mr. Nguyen has sent his four children to ivy-league colleges, however, he has sacrificed his health working day and night in that dusty bakery.
This computer doesn't make sense to me, it came without a manual.
雖然這兩個子句相當簡短，而且關係相當密切，但卻是個 run-on sentence。我們必須以句點來取代逗點。
sentence。這個「可怕的」句子只有一個獨立子句，主詞為 Carl Lewis，動詞為 made。
Knowing that millions of people around the world would be watching in person and on television and expecting great things from him -- at least one more gold medal for America, if not another world record -- during this, his fourth and surely his last appearance in the World Olympics, and realizing that his legs could no longer carry him down the runway with the same blazing speed and confidence in making a huge, eye-popping leap that they were capable of a few years ago when he set world records in the 100-meter dash and in the 400-meter relay and won a silver medal in the long jump, the renowned sprinter and track-and-field personality Carl Lewis, who had known pressure from fans and media before but never, even as a professional runner, this kind of pressure, made only a few appearances in races during the few months before the Summer Olympics in Atlanta, Georgia, partly because he was afraid of raising expectations even higher and he did not want to be distracted by interviews and adoring fans who would follow him into stores and restaurants demanding autographs and photo-opportunities, but mostly because he wanted to conserve his energies and concentrate, like a martial arts expert, on the job at hand: winning his favorite competition, the long jump, and bringing home another Gold Medal for the United States, the most fitting conclusion to his brilliant career in track and field.

逗點 + 小而美的連接詞 (and,
but, for, nor, yet, or, so)
My grandmother refuses to go to bed early, and I'm afraid she's going to catch a bad cold.

分號 + 大而醜的連接詞或其他連接副詞
(however, moreover, nevertheless, therefore, as a result,
consequently . . . ) + 逗點
My mother has stayed up late four nights in a row; as a result, she cannot seem to get well.
