I thought through it and I’d wager a stiff draught that it ought not be so rough, though as I’m taught, it’s nought to cough at that a sturdy, taut bough would snap under the weight of its idiosyncrasies.

In Anglophone school, We were taught as children "I before e, except after c." This works most of the time, but "reign" breaks the rule. It is not even word orgin as both recieve and reign come from French.

I still can't spell recieve and receipt

Hey, you got one of them right!

Oh man this is me with "exercise" and "exorcise."

I know it’s not wrong, but it would definitely give one away as a non-native speaker and come across very awkwardly.

Oh, no, it's wrong grammatically too, they just don't teach this unless you study linguistics. Most of all languages with fixed word order and some others have a natural order of adjectives. Tom Scott has a great vid about it.

Yes, Russian has an adjective order too. “A big old blue car” would be «большая старая синяя машина», saying «синяя большая старая машина» implies that “big old car” is a specific term.
