idiom

To satisfy an important basic standard or check. It means something is acceptable enough to continue, join, or be trusted.

  • Her proposal passed the litmus test.
  • This solution will pass the litmus test for safety.
  • Your answer should pass the litmus test of fairness.

Adinary Nuance

Pass the litmus test is stronger than just "be good enough". It suggests one clear standard that decides whether something is acceptable. Writers use it when they want to stress a decisive check, not a general opinion. It is similar to "meet the standard," but more vivid and metaphorical.
