How it's used

Carries a formal or literary tone despite being used in everyday speech to emphasize deep expertise or thorough understanding. It is often reserved for situations involving complex systems, technical knowledge, or long-term experience rather than simple familiarity with a person or a casual object.

Common phrases

Common mistake

Learners often mistakenly use it to describe knowing a person well, but it is almost exclusively applied to information, processes, or environments. Use 熟絡 for people instead.
