1. AVOIDING SENTENCE FRAGMENTS
Adapted by Algonquin College from content provided by Capital Community College and Professor Charles Darling.

2. Incomplete Verbs
A sentence fragment tries its best to be a sentence, but it just can’t make it. It’s missing something.
Often, it’s missing a verb or part of a verb string:
John working extra hard on his hook shot lately.
Here, for instance, we’re missing an auxiliary — has been, in this case, probably — that would complete the verb string and the sentence.

3. Incomplete Verbs
Spending hours every day after school and even on weekends.
This time, we’re missing a whole verb. Spending is a participle wanting to modify something, but there is no subject-verb relationship within the sentence.

4. Avoiding Sentence Fragments
Sometimes a sentence fragment can give you a great deal of information, but it’s still not a complete sentence:
After the coach encouraged him so much last year and he seemed to improve with each passing game.
Here we have a subject-verb – in fact, we have two of them – but the entire clause is subordinated by the dependent word after. We have no independent clause.

5. Avoiding Sentence Fragments
Be alert for strings of prepositional phrases that never get around to establishing a subject-verb relationship:
Immediately after the founding of the College and during those early years as the predominant educational institution in Northern Ontario.
Again, be careful of sentences which give their share of information but still don’t contain a subject and verb.
