Expert writing Tips
Best practice
When referring to a person from whom you learned, use "from whom I learned" or "who taught me" to maintain grammatical correctness in formal writing.
Common error
Avoid using "who I learned" directly; it's grammatically incorrect. Instead, use the correct relative pronoun structure with 'from whom' or rephrase the sentence to use a verb like 'taught'.

Ludwig's WRAP-UP
The phrase "who I learned" is a grammatically incorrect attempt to form a relative clause specifying a person from whom one has learned. While it appears with some frequency in informal contexts such as news media, as seen through Ludwig examples, it's not appropriate for formal writing. Ludwig AI emphasizes that standard English requires alternatives like "from whom I learned" or a rephrasing such as "who taught me". When aiming for clarity and grammatical precision, especially in academic or professional settings, it's crucial to avoid "who I learned" and opt for a correct alternative.
