Necessary

Adjective describing something that must be done or is essential, vital, or indispensable. It signifies an unavoidable requirement, a crucial element, or a situation where omission would lead to undesirable consequences. The concept emphasizes importance and a lack of optionality, suggesting a dependency on the thing or action in question for a desired outcome or basic functionality. This could relate to needs, conditions, or requirements. A 'necessary' element supports an action, preventing the absence of a goal.
