Expert writing Tips
Best practice
Always use "is determined by" or "is based on" instead of "is determined on" for grammatically correct writing. The preposition 'by' indicates the cause or means, while 'on' is typically used for location or time.
Common error
Avoid using "on" after "determined" when indicating the basis for a decision or outcome. "On" implies a surface or a date, not a causal relationship. Instead, use "by" to show the determining factor.
