rice cake
飥 centers on a specific type of food: a rice cake. The meaning is narrow and concrete, referring to a traditional pounded-rice treat.
飥 combines the food radical 飠 with 乇, which likely contributes the sound. The exact historical development is uncertain, but the character is used for a specific rice cake.
The left side 飠 is food, and the right side 乇 looks like a simple mound. Picture a mound of pounded rice shaped into a cake: 飥 is a rice cake.
For タク, imagine a tack stuck into a soft rice cake to hold a decoration: tack -> タク, and the rice cake is the food 飥.
