The kanji 落 primarily conveys the idea of "falling," "to drop," or "to fall down." It implies a downward movement or a separation from a higher position. It can also extend to meanings related to omission, decline, or a conclusion. The core concept is something ceasing to be in its original state or place due to detachment, displacement, or the passage of time.

The kanji 落 is a phono-semantic compound. The left side is the radical 氵（さんずい - water), which indicates a connection to liquid or flowing. The right side is 各, which serves as a phonetic component and gives an indication of the sound. The original meaning might be related to things dripping or falling into water. This character developed to represent a broader meaning of "falling" or "dropping" over time, incorporating the concept of something detaching or separating, moving downward, and eventually evolving to encompass broader uses like "omission" or "decline."
