Ludwig's WRAP-UP
In summary, "it was asserted by" is a grammatically sound phrase best suited for formal writing, particularly in academic, scientific, and professional settings. While Ludwig confirms its correctness, remember that its formality may be excessive in casual contexts. Consider alternatives like "it was claimed by" or "it was stated by" for more neutral tones. When using this phrase, ensure you're emphasizing the formal nature of the statement and attributing it clearly to the source. Overusing it in everyday language can sound unnatural, so be mindful of your audience and context.
