This page provides the basic foundations of English grammar and punctuation, which are necessary to all academic writing. Here you will find a review of punctuation, details on common mistakes, such as sentence fragments, run-ons and comma splices, along with useful resources to further your skills in written English.
A sentence fragment consists of a group of words that appear to be a sentence but are in fact not. In order to be a sentence, there needs to be at least one independent clause - a group of words that contain both a subject and a finite verb and can therefore stand on their own.
"Gone to the supermarket to buy apples." → "I went to the supermarket to buy apples."
A run-on sentence, also known as a fused sentence, occurs when you put two complete sentences (a subject and its predicate and another subject and its predicate) together in one sentence without connecting them properly, such as with a conjunction (and, but, if).
"The football match was cancelled however many fans turned up to the stadium" → "The football match was cancelled; however, many fans turned up to the stadium", or "The football match was cancelled. However, many fans turned up to the stadium."
A comma splice is a particular type of run-on sentence in which two independent sentences are connected by only a comma. When you use a comma to connect two independent sentences, it must be followed by a conjunction (connecting word), such as "and", "or", "yet", "so", and "but". Alternatively, you can separate the independent clauses using a full stop "." or semi-colon ";". The comma splice is a common mistake in English writing. It has to be noted that commas can join independent clauses in many other languages, and this can lead non-native English speakers to make this mistake.
"The desk needs cleaning, the computer needs updating" → "The desk needs cleaning, and the computer needs updating", or "The desk needs cleaning. The computer needs updating".
Unlike the types of problematic sentences discussed above in this box, rambling sentences are not grammatically wrong; nonetheless, they are highly undesirable, and should be avoided. Always try to write short and clear sentences.
"Writing long sentences can impair the clarity of your writing, therefore rendering your text unaccessible and difficult to follow, which is not a desirable thing as you should aim at helping the assessor engage with the text, or s/he may mark you down, while all you need is to write shorter sentences, although it can be difficult if the ideas relating to your text are confused, and you should therefore first work to clarify them."
"Short sentences contribute to make a text accessible, easy to follow and engaging. Failure to do so in an assignment may compromise its mark. In order to write short and clear sentences you need to first clarify your ideas."
Proofreading is a valuable part of the writing process and time should be put aside to ensure this stage is effectively undertaken. It is best to proofread a few times, focusing on a particular aspect each time, such as critical analysis, then coherency and fluidity of the essay structure, and lastly grammar and punctuation.
Here is a handout out to help in proofreading for common grammatical errors:
The English language can be a difficult one when certain words can sound the same but have very different spellings and in turn different meanings.
