The word "appallment" is not actually a correct spelling. The correct spelling is "appalment," pronounced /əˈpɔːlmənt/. The word describes the act of being appalled or shocked by something, and is derived from the verb "appall," pronounced /əˈpɔːl/. The incorrect spelling, "appallment," may have arisen from a mistaken assumption that the suffix "-ment" can be added to any verb to make a noun form. However, the correct suffix in this case is "-ment" rather than "-ment."
