Answers to Part 2 of Discovering useful structure on Page 44.
T: After finishing the exercise, do you know what the nominative absolute construction is?
Let the students think of it for a minute.
T: The nominative absolute construction is a free standing (absolute) part of a sentence that describes or modifies the main subject and verb. It is usually at the beginning or end of the sentence, although it can also appear in the middle.
Step II Grammar
T: This is the grammar in this unit. Please go over all the sentences in Part 1 on Page 44. Sum up how the structure can be used in this pattern. A way to remember or determine what constitutes a nominative absolute is to add a verb. You can always create a sentence out of a nominative absolute with one verb.
e.g. Their manes flowing, the horses ran from the burning barn. Nominative absolute: "Their manes flowing." Add a verb: "Their manes were flowing."
e.g. Stephen, his mind taxed, searched frantically for a dictionary.
Nominative absolute: "his mind taxed"
Add a verb: "His mind was taxed."
Similarly, one can break the absolute off, add a verb and make two sentences. ("Stephen searched frantically for a dictionary. His mind was taxed.") Can you understand me?
Ss: Yes.
T: OK. Let's go on. Absolute constructions consist of a noun and some kind of modifier, the most common is participles. Because they often come at the beginning of a sentence, they are easily confused with dangling participles. But an absolute construction modifies the rest of the sentence, not the subject of the sentence (as a participial phrase does). You can use absolute constructions to compress two sentences into one and to vary sentence structure as a means of holding a reader's interest. Here are some examples:
e.g. No other business arising, the meeting was adjourned.
The paint now dry, we brought the furniture out on the deck.
The truck finally loaded, they said goodbye to their neighbors and drove off.
The horse loped across the yard, her foal trailing behind her.
T: Constructions like these are used more often in writing than in speaking, where it is more common to use a full clause: When the paint was dry, we brought the furniture out on the deck. There are, however, many fixed absolute constructions that occur frequently in speech:
e.g. The picnic is scheduled for Saturday, weather permitting.
Barring bad weather, we plan to go to the beach tomorrow.
All things considered, it's not a bad idea.
T: Notice that absolute phrases contain a subject (which is often modified by a participle), but not a true finite verb.
e.g. Their reputation as winners secured by victory, the New York Liberty charged into the semifinals. The season nearly finished, Rebecca Lobo and Sophie Witherspoon emerged as true leaders. The two superstars signed autographs into the night, their faces beaming happily.
T: When the participle of an absolute phrase is a form of to be, such as being or having been, the participle is often left out.
e.g. The season (being) over, they were mobbed by fans in Times Square. (Having been) Stars all their adult lives, they seemed used to the attention.
T: Another kind of absolute phrase is found after a modified noun; it adds a focusing detail or point of focus to the idea of the main clause. This kind of absolute phrase can take the form of a prepositional phrase, an adjective phrase, or a noun phrase.
e.g. The old firefighter stood over the smoking ruins, his senses alert to any sign of another flare-up. His subordinates, their faces sweat-streaked and smudged with ash, leaned heavily against the firetruck.
They knew all too well how all their hard work could be undone in an instant.
T: It is not unusual for the information supplied in the absolute phrase to be the most important element in the sentence. In fact, in descriptive prose, the telling details will often be wrapped into a sentence in the form of an absolute phrase:
e.g. Coach Nykesha strolled onto the court, her arms akimbo and a large silver whistle clenched between her teeth. The new recruits stood in one comer of the gym, their uniforms stiff and ill fitting, their faces betraying their anxiety.
T: A noun phrase can also exist as an absolute phrase:
e.g. Your best friends, where are they now, when you need them?
And then there was my best friend Sally--the dear girl--who has certainly fallen on hard times.
T: It might be useful to review the material on Misplaced Modifiers because it is important not to confuse an absolute phrase with a misplaced modifier.
