rice snacks
糢 centers on rice-based snacks, specifically small, shaped treats made from rice. The meaning is narrow and concrete, without broad abstract extensions.
糢 combines 米 (rice) with 莫, which likely contributes a phonetic element. The character is used for rice-based snacks, but its exact historical development is uncertain.
The left side is 米 (rice), and the right side 莫 looks like a big sun setting behind grass. Imagine shaping rice into snacks while watching the sunset: 糢 is a rice snack.
For ボ, picture a bowl of rice snacks: bowl -> ボ, and you're eating a bowl of 糢.
