This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
The exact historical development is uncertain. The modern form combines 衤 (clothing) with 賴, but the original semantic and phonetic roles are unclear.
The left side 衤 suggests clothing, and the right side 賴 is a complex shape. Without a clear meaning, picture a mysterious garment whose purpose is unknown.
For ライ, imagine a mysterious garment lying on the ground: lie -> ライ, but its meaning remains hidden.
