to spread (name, news), to be knowing
摛 centers on spreading or disseminating something, especially information like a name or news, so that it becomes widely known.
摛 combines 扌 (hand) with 离, which likely contributes the sound and may relate to spreading or separating. The exact historical development is uncertain.
The hand radical 扌 beside 离 suggests a hand spreading something outward, like scattering seeds or news.
For チ, imagine a hand spreading cheese across a cracker: cheese -> チ, and the hand spreads it evenly.
