liquor jar
罍 centers on a large container for holding alcoholic drinks: a liquor jar or sake barrel.
罍 combines 畾 (a triple-field shape, possibly suggesting stacked containers or abundance) with 缶 (a jar or pot), together indicating a large vessel for liquor. The exact historical development is uncertain.
The top 畾 looks like three stacked fields or containers, and the bottom 缶 is a jar. Picture a huge jar filled with sake, as tall as three stacked barrels.
For ライ, imagine a line of liquor jars: line -> ライ, and each jar is filled with sake.
