Expert writing Tips
Best practice
When aiming to express that something is supported by evidence, ensure the preposition used appropriately reflects the relationship between the evidence and the claim. Consider "by" rather than "for" to indicate support from evidence.
Common error
Avoid using the preposition "for" after "substantiated" when referring to evidence supporting a claim. The correct preposition in this context is often "by". For example, say "The claim was substantiated by the evidence" instead of "The claim was substantiated for the evidence".
