Appropriate vs. Necessary: What's the Difference?

Edited by Janet White || By Harlon Moss || Updated on November 8, 2023
"Appropriate" pertains to what is suitable or fitting for a specific situation, while "necessary" refers to what is essential or required.

Key Differences

"Appropriate" describes something suitable or proper in a given circumstance. It implies that there is a choice among many options, and the most fitting one is chosen. On the other hand, "necessary" denotes something that is indispensable or required, suggesting there may be no suitable alternatives.
When one considers whether an action is appropriate, they are gauging it against social norms or specific conditions. Conversely, determining if something is necessary involves assessing its importance or essentialness to a goal or function.
An appropriate measure may be one of several effective options, chosen based on context or propriety. In contrast, a necessary measure is one that must be taken to achieve a result, without which the outcome cannot be realized.
Choosing an appropriate dress for a wedding is about matching attire to the occasion, where there are many correct choices. However, wearing a dress to the wedding, if specified, becomes necessary for adherence to the event's dress code.
Appropriateness often involves subjective judgment, where different people may have different opinions based on personal or cultural standards. Necessity, however, is more objective, where the required nature of something can be more universally agreed upon.
