Expert writing Tips
Best practice
Always use "convinced by" or "convinced of" instead of "convinced with". The preposition 'by' indicates the source of persuasion, while 'of' denotes the content about which one is convinced.
Common error
Avoid using "with" after "convinced". It's a common mistake that undermines the credibility of your writing. Always double-check your preposition usage in formal contexts.

Ludwig's WRAP-UP
The phrase "convinced with" is a common grammatical error. The correct forms are "convinced by", indicating the source of persuasion, and "convinced of", indicating the object of persuasion. Although Ludwig identifies numerous examples, it's crucial to recognize that these instances represent incorrect usage.

Therefore, writers should be diligent in ensuring they use the correct preposition to maintain grammatical accuracy and credibility. As Ludwig AI suggests, the best alternative for "convinced with" is ""convinced by"".
