display food for show only, sacrifice
飣 centers on food presented for display or ritual offering rather than for ordinary eating: food arranged for show or as a sacrifice.
飣 combines the food radical 飠 with 丁, which likely contributes a phonetic element. The character is associated with displaying or offering food, but the exact historical development is uncertain.
The food radical 飠 beside 丁 suggests food arranged neatly on a stand or table for display or ritual offering.
For テイ, imagine a table (テーブル, tēburu) set with food for display: the first syllable テイ of テーブル cues the reading.
