'Trouble' is just 'fun' spelled incorrectly.

But no, I don't generally have trouble with spelling mistakes.

Anyone who can only think of one way to spell a word obviously lacks imagination.

They spell it Vinci and pronounce it Vinchy; foreigners always spell better than they pronounce.

Nothing you can't spell will ever work.

It is a damn poor mind that can think of only one way to spell a word.
