allure, entice
啗 centers on drawing someone in through temptation or persuasion: to allure or entice.
啗 combines 口 (mouth) with 臽, which likely contributes the sound and may relate to a pit or trap, suggesting luring someone in with words or taste.
The mouth 口 beside 臽 (a shape associated with a pit or trap) suggests using words or taste to lure someone into a trap: alluring or enticing.
For タン, imagine a tan, tempting dessert that entices you to take a bite: tan -> タン, and your mouth is allured.
