Ludwig's WRAP-UP

The phrase "were not derived" is a grammatically correct and frequently used expression, particularly in scientific and formal contexts. As Ludwig AI confirms, it serves to negate a potential source or origin, often to clarify the true source or to correct a misunderstanding. It's crucial to explicitly state the actual source when using this phrase to maintain clarity. While "were not derived" implies a different source, it doesn't necessarily mean complete independence, so it's important to consider indirect influences as well. Alternative phrases like "did not originate from" or "were not sourced from" offer similar meanings with slightly different nuances.
