Duncan's guide on how to write accents (in english)!

[DuncanDill]

These are just what I find to be good, so feel free to do what you like.
Original:
It was the Sun, and not a boy, whose heat stripped me naked; as for you, Euripides, when you were kissing someone else's wife the North Wind screwed you. You are unwise, you who sow in another's field, to accuse Eros of being a snatch-thief.

Troll:
It were Sun, not boy, who heat strip naked; for you, Euripides, when you kiss other wife the North Wind screw you. You unwise, you who sow in other field, accuse Eros being snatch-thief.

Remove articles and conjunctions. Remove tense, and simplify some words.

Orc:
It was the Sun, an' not a boy, 'o heat is strippin's me's naked; as fo' ya, Euripides, when you was kissin's someone else's wife the North Wind screwed ya. Ya're unwise, you who is sowing in anofer's field, to accuse Eros of bein's a dirty bugger.

Add dirty language, and remove the consonants of words ending with n_. on verb change to present tense, and add a 's on the end. Also add a 's on the end of first person. replace th with an f. Replace who with 'o and you with ya.

Dwarves:
T'was the Sun, and not a lad, 'os 'eat stripped me to scud; as foer yeh, Euripides, when you were kissin' someone else's lassie the north wind screwed you, ken? Yeh be unwise, yeh 'o sow in another's field, to accuse Eros of bein' a limmer.
Much like orcish but a bit fancier and with some scottish words. If you want to emphasise a sentence, or end a paragragh ken works well. Though, be careful not to overdo this, as it can be a bit strange looking at times.

Magic:
Non puer erat Sol, nudum me nudasti; Euripides, tibi, Boreas advenienti, cum alienam uxorem oscularis. Insipiens esto, qui in alieno agro seminas, ut Erotem raptorem accuses.
Change up the word order and change it to latin. Thats about it!

More coming soon, feel free to put your own prose here!

I don't think those are good examples. The Troll and Orc speech strike me as particularly fake. In order to write convincing dialogue for these simple-minded races, one needs to mind not just the choice of words and grammar, but also the syntax and the very subject of the utterance.

Specifically, I would find it totally out of character if a Troll spoke in long sentences with subordinate clauses. Furthermore, out of the multitude of concepts referenced in this quote, a Troll would barely understand the idea of wearing clothes, and the rest would be just inconceivable to him. References to Aesop's fables are totally out of the question.

If a Troll attempted to express something in this vein, it would rather sound like this:

The cub no take my blanket! I take blanket off 'cause the Sun warm! You say the cub steal, you stupid! You steal other's mate, not fair!

An Orc would be capable of more sophisticated syntax (and mostly correct grammar), but he certainly wouldn't have the wit for jokes, nor would he be amused by them. An Orc would rather respond with insults and threats:

You dare to say that the dirty goblin stole my cloak! You liar! I took it off 'cause I don't need no cloak when the Sun shines so hot! You are very foolish to look for a fight with me. I know you trick your tribesmen to mate with their wives. You are too weak to take them openly like a true warrior! You will regret your words when I rip your tongue off and feed it to the goblins.

Yeah I get what you mean with the examples, but orcs are supposed to sound stupid (as said in prose wiki)
