I have two issues I need advice on. One is about the article preceding "usurper", and the other is on dangling modifiers/possible run-on sentence. Google searches have shown both to be acceptable, but I'd like to receive an answer from a more credible source (like here). Example sentence: (Dialogue) "You could never be forced to live in fear of a Usurper attack." Is this an exception due to the pronunciation of the word? I've taken a look at the link for "A vs An" that was provided in another thread, but figured I'd throw this in here just to be certain. ____________ I'd also like to receive some input on the following sentence. I'm told it suffers from 'dangling modifiers'. I've researched dangling modifiers and I'm still hazy on what aspects of this sentence are in need of correction. "Sinking into the vinyl cushion, Hal observed the driver shouting obscenities, flailing and stewing in rapidly deteriorating temperament as he wrestled through traffic at an agonizing crawl." What part of this sentence is a run-on? I've been told it suffers from that as well. Any additional advice is most welcome.
