Appended parts may be joined asyndetically, and in this case they are marked off graphically by a comma or a dash. They may be also joined by some conjunctions (and, or), or else by explanatory words (namely, that is, i.e. (= that is), to wit, for example, for instance); also by intensifying particles (almost, especially, etc.).
Language makers,that is ordinary speakers, are not very accurate thinkers.
He had discovered that he had a talent for mathematics -almost a genius for it.
Another way of linking the appended modifier to its headword is the repetition of the same part with modifying words.
My object is secure happiness- the happiness of both of us.
There are three structural types of appended modifiers.
1. The most common case of an appended modifier is when a different word or even a different morphological form refers to the headword. Standing for identical notions, the appended part gives a fuller and more detailed nomination of the same concept. In some way appended modifiers of this type resemble appositions, only unlike appositions, they may refer to words of non-nominal nature (verbs, adverbs). Even referring to nouns, they never qualify words, but particularize the notion.
Yet it worried her,this queer intensity of Hughie’s.
I used to do as Jean Jacques did— lie down on my boat and get it glide whereas it would.
(appended predicate with dependent words)
Hughie wanted to be a star,a footballer in the big league.
And we’ll talk it over,every bit of it.
2. Appended modifiers of the second type form a string of homogeneous parts referring to a headword with a general meaning (thing, problem, question, etc.). Here again the appended modifiers may refer to different parts of the sentence.
She kept up her music, she read an awful lot - novels, poetry, all sorts of stuff .
She was allowed to choose things from the shop; jam, or paste, or biscuits, or the slab cake.
3. Appended parts of the third type - with a repeated headword - usually have an emphatic force.
There was only one road: the main road, the road that struck due east.
He had his pride of course, the natural pride of a liberal enlighted man.
He had been a fool, a presumptuous fool.
In silence they stood, in mortal silence.
(appended adverbial modifier)
The emphatic force is often manifested by adverbs of degree, intensifying particles (just, even, especially, particularly, at least, in particular), or modal words (in fact, indeed, etc.). The explanatory function is carried out by modifying words or attributive clauses.
In one place Winterbourne found ... a French-woman with two starved children living in a cottage with nothing but straw -literally nothing but straw...
They assured him that they were the only men- or almost the only men - left alive...
