This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
The exact historical development of 侌 is uncertain. It appears to combine 今 and 云, but the original semantic or phonetic role of these components is unclear.
The top 今 suggests 'now', and the bottom 云 suggests 'cloud' or 'say'. Without a clear meaning, picture a fleeting cloud that is here now and gone in a moment, leaving its meaning uncertain.
For イン, imagine an inn where the sign is so faded you cannot read its meaning: inn -> イン, and the kanji remains mysterious.
