The Definition of Preventive
Preventive means “designed to keep something undesirable from occurring.” Yes, it has the exact same definition as preventative. Preventive often refers to various forms of medicine that can prevent disease. The word preventive can also be used as a noun. In this case, it means “a medicine or other treatment designed to stop ill health from occurring.”
If you look up the words preventive and preventative, you’ll find that they have exactly the same definition. Some dictionaries, like Merriam-Webster, place a direct link to the entry for preventive rather than including a separate entry for preventative. Both words mean the same thing.
The Etymology of Preventative and Preventive
The -ive suffix was added to the verb prevent around the year 1635. Preventative evolved as a variant spelling of preventive around the same time. However, preventive has always been the more popular option.
Of course, there’s some variation between American English and British English. In British English, the word preventative is nearly as popular as the word preventive. Style guides such as The New York Times, Garner’s Usage Guide, the AP Stylebook, and The Chicago Manual of Style all prefer the shorter version.
The Bottom Line
Both variants are valid words that have the same meaning. Still, preventive is generally preferred. The editor of Merriam-Webster’s Learning Dictionary even gave some advice on this topic, mentioning that some writers and editors believe the word preventive is better and more correct than the word preventative. They went on to say that these beliefs aren’t true, but in order to avoid conflict, it’s best to use preventive instead.
