What character might "lia" [Ĩia⁵³] meaning "lick" be? I have this dictionary entry from《广安方言与民俗词典》:

□
lia3
①指舔、舐的意思，用舌头接触东西或舔吃东西。②也指巴结，讨好。例：他最喜欢lia3有权有势的。“lia3 lia3糖”，指棒棒糖。例：拿颗lia3 lia3糖去让他含倒，哄倒起莫哭。

I have seen lia3 substitued with:

甪

and



While  does share the idea of brown-nosing (巴结，讨好) it's unlikely that it would mean lick.
Maybe a mutation of  would make more sense especially with the whole 湖广填川 thing.
Any ideas?
