The kanji 恒恒 is a phono-semantic compound (形声文字). The left side is "忄" (りっしんべん - "heart" or "mind"), which provides the semantic component, indicating that the meaning is related to state of mind, character, or the mind's ability to maintain something. The right side is 亘 (亘 - "to span," "to extend over"), which provides the phonetic component, suggesting the sound and also contributing to the idea of something continuing or extending through time and space. Therefore, the combination suggests the consistent or constant nature of the mind or state of being.
