This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
誏 combines 言 (speech) with 良, which likely contributes the sound. The exact historical development and original meaning are uncertain.
The left side is 言 (words) and the right side is 良 (good). Picture good words being spoken, but the true meaning is unclear.
For ロウ, imagine a low, rumbling sound of speech: low -> ロウ, as the 言 component hints at talking.
