Is it just me or is this getting worse? Some of this stuff makes me wonder when the writer is going to be graduating from high school.
Calling your characters "Wharrior" and "Frehnzy" doesn't make your story cool. Neither does a reference to a "childe" or a "songe" unless your story is set in a period when that spelling was used. "Sylvyr" and its permutations don't impress me either. Spell things correctly. If you want to be different, use foreign names, or for SF and fantasy you can make something up from scratch. The universe should charge a nickel -- per letter, multiplied by the number of copies of the book/story printed -- for every extraneous "H" and "E" and for every "Y" pasted on where another vowel should be.
Apostrophes, linguistically, indicate a glottal stop. If that's not what you want, don't use them. Anne McCaffery gets a pass because her dragon riders actually shortened their names when they got their dragons, so her apostrophes indicated legitimate contractions. If your word isn't a contraction and doesn't have a glottal stop, leave the apostrophes out. Names like "Jo'nathan" or "T'revor" don't look cool. Making up a name doesn't help -- if you pronounce "Lerin'elia" the same way you'd pronounce "Lerinelia," leave out the apostrophe. And seriously, there are so many writers nowadays who think throwing in a pointless apostrophe is just too cool that even if you do mean to indicate a glottal stop in the middle there, most people will assume you're a teenager trying to sound cool anyway.
Capitalizing a blah noun won't make it any less blah. If your character is carrying the Cup, the Candle and the Flask into the Hall where the Warrior will perform the Ceremony, you need to go back and rethink a few things. If something is that special, it'll probably have a name. Think of one and then use it. If it's not, then it doesn't require a capital, so don't use one.
Caveat: if you're using a chunk of a longer proper name, you can capitalize that. So for example, I'm from the United States of America, and calling it "the States" is legitimate because "States" is part of a proper noun. Having your hero wield "the Sword," though, just makes me eyeroll unless you told me earlier that it's actually "the Barliman Sword of Truth" or whatever.
Putting an English word into italics doesn't make it sound foreign. If your character speaks a foreign language -- either a realspace language or one you've made up for your SF or fantasy book -- then either use that language with italics or translate it into English without italics. English in italics just makes it look like you're going through the text with a hilighter, marking the cool parts for us so we know they're cool. It doesn't work.
Yes, I've been reading. This has been bugging me more and more recently, and I just ran across Nathan Bransford's post on readers' pet peeves. My comment got kind of long [cough] so I brought it back here.
I'm expecting to see a Syl'vyr Childe named Cuhr'se wander through the Door with an engraved Knife any time now. [headdesk]
