2 of those aren’t real words, and one of them is an abbreviation. So I suppose it could be argued that you can sum up this dynasty in 0 words.

Arth and Darth are words. They’re proper nouns, which are words.

And abbreviations are words too.

You amateurs bug me.

Go Arth!

Well, Darth is part of a proper noun, I guess, but. Arth is part of the word “arthexis,” so not a word itself. Abbreviations are the little lost step-nephew of words. Do you play Blognomic professionally? But I’m glad there’s a place to discuss minutiae like this.

Not amateur BlogNomic players - amateur Grammar Nazis.

Hardly, I was just thinking outside the box to add spice to an otherwise inane post. It’s hard for a grammarian on this site, just look around. Why did you capitalize “arth?” . . . just because I want to know the policy on capitalizing non-capitalized proper nouns at the beginning of sentences, which I can surely only get from self-proclaimed proffesional grammar Nazis.

Furthermore, my nickname is all lowercase, so, no sense in capitalizing it.

The Arth instead of arth just seems to be standard around here.

Furthermore, it happens to be the first word of a sentence.

Please read my last comment.

@Bucky: That’s not even a sentence.

Yes it is.

Subject: Arth
Verb: versus (which is in fact a verb, just a strange one)
Object: Darth

“Versus” is a preposition. Cf. “against.” Prepostitions are not verbs. A sentence must have a verb. Neither “Arth” nor “Darth” is a verb. Q.E.D. it isn’t a sentence.

Alright then, after several dynasties of looking it up, I have decided that the full three words are together just one noun, e.g. how the name of a lawsuit can be used as a noun.
