Meaning

To make sense; to be convincing; to be satisfying. The feeling of something finally clicking and settling in one's understanding.

The affirmative counterpart of 腑に落ちない. 腑 (viscera) is used as a metaphor for the seat of emotion and understanding, so something 'dropping into' the 腑 means it has been fully absorbed and accepted. Commonly used to describe the moment of comprehension after confusion, or to affirm that an explanation was genuinely satisfying.

Examples

1. 先生の例え話を聞いて、ようやく腑に落ちた。 After hearing the teacher's analogy, it finally clicked.
2. 長年疑問に思っていたことが、その一言で腑に落ちた気がした。 Something I'd been wondering about for years suddenly made sense with that one remark.
