FAQ
Frequently Asked Questions
Yes, though less common than its noun form. As an adjective, it means 'required as a prior condition' (e.g., 'prerequisite knowledge').
A 'requirement' is anything that is needed. A 'prerequisite' is a specific type of requirement that must be met *before* something else can happen. All prerequisites are requirements, but not all requirements are prerequisites.
Both are widely used and generally acceptable. 'Prerequisite for' is slightly more common, especially when referring to a thing. 'Prerequisite to' is often used with gerunds (e.g., 'a prerequisite to graduating').
No, they are often confused. 'Perquisite' (often shortened to 'perk') means a special right or benefit enjoyed as a result of one's position. 'Prerequisite' is something required beforehand.
