Ludwig's WRAP-UP

The phrase "a number of knowledge" is generally considered grammatically incorrect because "knowledge" is an uncountable noun. Ludwig AI confirms this assessment. While the intent is to express a quantity or scope of knowledge, better alternatives include "a range of knowledge", "a wealth of knowledge", or "a great deal of knowledge". When precision is needed, specifying "a number of knowledge areas" or "domains" can be accurate. Although it appears in various sources, including news and scientific articles, it's best to avoid it in formal writing to maintain grammatical correctness.
