The 25 most commonly misspelled words is a list that has circulated among businesses for decades. It contains the words business people must spell correctly when they use the words in a specific context.

For words that may have variant spellings, such as "judgment" and "judgement," American business supervisors and editors will change "judgement" to "judgment" in all cases, possibly believing that the writer is ignorant of standard spelling conventions. British business people may change "judgment" to "judgement."
