Preventive vs. Preventative
English is a language with numerous pairs of words that sound similar but have very different meanings. However, there are also pairs that sound similar and have similar meanings. One such pair is preventive and preventative, which have similar meanings but differences that prevent them from being synonyms. This does not stop people from using the words preventive and preventative interchangeably. Let us take a closer look.
Preventive
In the medical world, particularly in medicine, the word preventive has great significance and use. Drugs used to prevent the onset of a disease or play a role in delaying a disease are commonly referred to as preventive drugs. In industries, preventive maintenance is a periodic checkup or maintenance procedure carried out at regular intervals to ensure that machines and tools continue working smoothly, preventing work stoppage due to avoidable faults or breakages. Thus, preventive is a word that describes something helpful in preventing the occurrence of an undesirable event.
Preventative
It is a fact, and dictionaries around the world corroborate this, that preventive is the adjective traditionally used for anything that prevents an undesirable event such as disease or breakdown. However, lately, preventative has increasingly emerged as an alternative for preventive. The use of preventative has increased so much that about a third of users are freely using it in place of preventive. Preventative is also seen in the content of many websites. There are cases where the two words have been used in the same sentence, with preventive as an adjective and preventative as a noun.
If we go by logic, representative comes from represent, and so the choice should be preventative, as it comes from prevent, and not preventive. However, logic has only limited place in the English language.
