How it's used

Focuses specifically on the depth of knowledge or skill acquired over time, often implying a long-term accumulation of experience. It is frequently used to explain why someone excels at a complex task or picks up new related skills quickly. Unlike basic knowledge, it suggests a structural depth that supports further development.

Common mistake

Do not confuse this with 基礎, which is a more general term for any kind of foundation or basis. 根底 carries a stronger nuance of personal background, training, or inherent capability developed over time.
