This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
譒 combines 言 (speech) with 番, which likely contributes the sound. The exact historical development is uncertain.
With 言 (speech) and 番 (number/turn), imagine someone speaking in turns or spreading words, but the exact meaning is unclear.
For ハ, picture a speaker laughing 'ha!' as they spread words: ha -> ハ.
