ancestral shrine, embroidery, (ghost kanji)
袮 is a rare kanji with unclear standalone meaning. It is listed with senses of ancestral shrine and embroidery, but it is also noted as a ghost kanji, so its actual usage is uncertain.
The exact historical development of 袮 is uncertain. It combines 衤 (clothing) with 尓, but the original semantic and phonetic roles are unclear, especially given its ghost kanji status.
The clothing radical 衤 beside 尓 might suggest embroidered garments used in an ancestral shrine, but treat this as a loose visual hint rather than a reliable meaning.
For デイ, imagine a day at an ancestral shrine where embroidered robes are displayed: day -> デイ, and the robes are the 衤 part of 袮.
