Combine the pair of sentences by changing one into an appositive. Remove all unnecessary or repeated words. Set the appositive off with commas.
Suddenly the navigator noted an obstacle straight ahead. The obstacle was a large iceberg.
- An appositive is a noun or a pronoun that is placed beside another noun or pronoun to identify or describe it.
- Appositives often act as clarifiers as that provide necessary identification to nouns or pronouns.
- Appositives usually follow the words they identify or explain; however, for emphasis an appositive may come at the beginning of a sentence.
e.g. Our teacher, Mrs. Walworth, has received a special award.
- In addition, a writer may use an appositive phrase. This phrase consists of an appositive and any modifiers that accompany the appositive.
e.g. The Alaska moose, the llargest deer in the world, inhabits the Kenai Peninsula.
So, to rewrite the above-mentioned sentence using an appositive, the writer can change the last sentence into this construction:
Suddenly, the navigator noted an obstacle straight ahead, a large iceberg.
[Note that identifying what to use as an appositive is often easy because one noun or pronoun will be repeated. The repeated noun/pronoun is the word to eliminate and then place the descriptive or explanatory words after the first noun/pronoun.]
