I studied modifiers this morning and found some interesting stuffs.

Then:
Summative modifier: https://grammar.about.com/od/rs/g/summat ... erterm.htm
A modifier (usually a noun phrase) that appears at the end of a sentence and serves to summarize the idea of the main clause.
Here are two sentences that contrast relative clauses and summative modifiers. Notice how the which in the first one feels 'tacked on':
Economic changes have reduced Russian population growth to less than zero which will have serious social implications.
Economic changes have reduced Russian population growth to less than zero, a demographic event that will have serious social implications.
Resumptivie Modifier: https://grammar.about.com/od/rs/g/resump ... erterm.htm
A modifier that repeats a key word at the end of a sentence and then adds informative or descriptive details related to that word.
Since mature writers often use resumptive modifiers to extend a sentence, we need a word to name what I am about to do in this sentence, a sentence that I could have ended at that comma, but extended to show how resumptive modifiers work."
The reader assumes from such messages that the writer has certain doubts, doubts that perhaps others may have, thus connecting, as possible fellow doubters, the writer and the reader.

So dogged were Frances Perkins’investigations of the garment industry, and her lobbying for wage and hour reform was persistent, Alfred E. Smith and Franklin D. Roosevelt recruited Perkins to work within the government, rather than as a social worker.

A. and her lobbying for wage and hour reform was persistent,
B. and lobbying for wage and hour reform was persistent, so that
C. her lobbying for wage and hour reform persistent, that
D. lobbying for wage and hour reform was so persistent,
E. so persistent her lobbying for wage and hour reform, that

Does this SC contain Absolute Phrase? Is "so persistent her lobbying for wage and hour reform" an absolute phrase because it has no verb?
