The spelling of the word "preventingly" can be confusing. It is pronounced /prɪˈvɛntɪŋli/ and is derived from the verb "prevent." The "-ing" ending is added to create the present participle form of the verb. The "-ly" suffix is then attached to create the adverb form, which means "acting to prevent." While the spelling may seem daunting, remembering the pronunciation and the origin of the word can help when using it in writing or conversation.
