I need an adjective that, when applied to the word "condition", makes that condition "unbreakable". In the text below the word "necessary" is used. Is there a better adjective in English for such case?

Somehow it has become a rule with time that anyone in our group who is stating a problem that he or she assumes to be taking place in our company must also provide at least one way of solving it. But why? Why should having a ready solution be a necessary condition for stating a problem? Anyone must feel free to bring up a problem even without having any idea how to solve it. In fact, if you already know how to fix a problem, then it doesn't look like a problem to you and you don't really feel the need to state it. However, the very reason why someone would would to state a problem at the meeting is because they don't know the solution while other members may.

  • You frequently see the phrase "requisite condition," although some people think that sounds a bit like legalese. Sep 12, 2020 at 12:34

    I like "necessary condition", perhaps because it speaks to my Maths background. You could perhaps change it to "requirement".

    I think the word "necessary" does the job. "Indispensable" might be more emphatic, but logically it's the same. Sep 12, 2020 at 13:08

    In almost all contexts, precondition means exactly the same as necessary condition, fundamental / unbreakable requirement. Aug 14, 2021 at 13:46

    You're probably looking for the word requirement.

Google defines:


a situation that must exist before something else is possible or permitted.

stipulation constraint prerequisite precondition requirement rule term specification provision proviso qualification necessity essential demand restriction

(emphasis mine)

Some of the similar words listed include 'necessity'. We hence should not repeat the adjective form.

'Condition' alone should do the job.

  • There is a distinction between a necessary condition and a sufficient condition. The use of the adjective is needed to distinguish between them. This answer is wrong. Aug 14, 2021 at 13:26
  • I don't see anything in the OP that would make the necessary / sufficient condition distinction relevant. A "sufficient" condition is simply a special case of "necessary" condition that implies there are no other necessary conditions (so long as that single condition is true, whatever logically follows from it will definitely also be true).
