Expert writing Tips
Best practice
When using "on spurious grounds", ensure that you can clearly articulate why the grounds are, in fact, false or misleading. Provide evidence or reasoning to support your assertion. For example, "The company dismissed the employee on spurious grounds of poor performance, despite consistently positive reviews."
Common error
Avoid using "on spurious grounds" when the issue is simply a matter of opinion or interpretation. "Spurious" implies an objective falsehood or deception, not just a disagreement. Therefore, do not say "The critic dismissed the film on spurious grounds of being unrealistic" when the critic simply had a different interpretation. Instead consider "The critic dismissed the film on subjective grounds of being unrealistic".
