What Is “Knowledge”?
In English, knowledge (noun, /ˈnɒlɪdʒ/) refers to the understanding, awareness, or information gained through experience or education.
“Knowledge is power.” — Francis Bacon
It is an uncountable noun, so we don’t say “a knowledge” or “knowledges.” Instead, we use phrases like “a piece of knowledge” or “areas of knowledge.”
