He spelled “martial” as “marshal”
He spelled martial as marshal
Of course you are only assuming he meant “martial.” (You fogot the period at the end of your sentence. Should we not take you seriously?)
But “marshal” is spelled correctly, so it’s not a misspelling.
Perhaps you meant to say he chose the wrong word. Oh, no, that could not be possible, since you apparently don’t make any mistakes.
(Just teasing.) ;>)
