Expert writing Tips

Best practice

Ensure the subject of the sentence is clearly defined to avoid ambiguity. It should be clear who or what is being "stumped".

Common error

Avoid using prepositions other than "by" after "stumped". Using prepositions like "at", "on", or "with" is grammatically incorrect. For example, don't say "stumped at the problem"; use "stumped by the problem".
