Pronunciation: [ɹˈʌnɒn] (IPA) 
The correct spelling of the word "runon" is actually "run-on", with a hyphen in between. This is because "run-on" is a compound word made up of two separate words, "run" and "on". In IPA phonetic transcription, "run" is pronounced as /rʌn/ and "on" is pronounced as /ɒn/. When combined together, "run-on" is pronounced as /ˈrʌn ɒn/. It is important to use the correct spelling to ensure clarity and understanding in written communication.
A run-on is a grammatical error that occurs when two or more independent clauses are not properly separated by punctuation or conjunctions. It is characterized by the lack of appropriate breaks or pauses between phrases or sentences. Instead of maintaining separate and distinct ideas, a run-on combines them into a single sentence, resulting in a confusing and disjointed structure.
An example of a run-on sentence could be: "I went to the store I bought some groceries." In this case, two independent clauses, "I went to the store" and "I bought some groceries," are joined without any punctuation or conjunction, making it a run-on.
Run-ons can also occur when phrases are incorrectly attached to independent clauses without proper separation. For instance, "She loves playing the piano she practices every day" combines the independent clause "She loves playing the piano" with the dependent clause "she practices every day" without any punctuation or conjunction.
To correct run-on sentences, one can use punctuation, such as a period or a semicolon, to separate the independent clauses. Alternatively, conjunctions like "and," "but," or "because" can be employed to join the clauses. The revised versions of the previous examples would be: "I went to the store. I bought some groceries" or "She loves playing the piano, and she practices every day."
The term "run-on" is derived from the combination of two words: "run" and "on".
The word "run" has Old English origins, coming from the Old English word "rinnan", which means "to flow" or "to move swiftly". Over time, it developed the meaning of "to proceed, to continue, or to operate".
The word "on" also has Old English roots, originating from the Old English word "on", which means "in a position above and in contact with" or "in continuation of or later than a particular thing".
In the context of grammar, the term "run-on" refers to a type of sentence that continues beyond its expected or proper length without proper punctuation, causing it to "run on" and potentially become confusing or difficult to understand.
