Consider this sentence:
Rome has—regarding the Egyptian war—an official goal, namely to weaken the Parthians.
You can see that "has" is interrupted. So there's some "suspense" (I call it "suspense" anyway) where the reader isn't sure (until after the interruption) whether it will be something like "Rome has many buildings" or something like "Rome has lost many soldiers". The word "has" can attach to some object that you have (he "has a stone") or it can be in a verb phrase or whatever (he "has been there").
I wonder about this "suspense" and whether it's OK.
I don't know how much "suspense" the average sentence has. I suppose that the "suspense" that I'm referring to here might be ubiquitous. The more frequently you see this "suspense", the less I should worry about it...right?
I saw this too (not sure if it's relevant):
A garden-path sentence is a grammatically correct sentence that starts in such a way that a reader's most likely interpretation will be incorrect; the reader is lured into a parse that turns out to be a dead end or yields a clearly unintended meaning. "Garden path" refers to the saying "to be led down [or up] the garden path", meaning to be deceived, tricked, or seduced. In A Dictionary of Modern English Usage (1926), Fowler describes such sentences as unwittingly laying a "false scent".
I also saw this example where the "and' after "crucible" could go in different directions (imagine the sentence said "forged in this crucible and in this situation"; I wonder if this kind of fleeting uncertainty and ambiguity is minor, innocuous, and commonplace.
The third part explores the new world of Roman politics forged in this crucible and how Blue Romans and Red Romans have both responded, in different ways, to the political pull of Rome's superrich.
