This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
嚟 combines 口 (mouth) with 黎, which likely contributes the sound. The exact historical development is uncertain.
The mouth radical 口 suggests a possible connection to speech or sound, but without a clear meaning, treat it as a mouth-related shape with an uncertain idea.
For リ, imagine a rare creature named Ri making a strange sound with its mouth (口): Ri -> リ.
