Common Pitfalls
One common confusion arises between “necessity” and “compulsion.” While both imply a force driving action, necessity often denotes something essential without negative connotations, whereas compulsion can carry implications of pressure or lack of choice.
Additionally, “obligation” may be mistaken for necessity. Although similar, obligations are typically duties owed to others based on rules or agreements, whereas necessities focus more on inherent need.
