I've tried a number of online and paper dictionaries (Chinese-Chinese character dictionaries) and I still can't find this character. Since I don't know how it's pronounced or what the right part is called, I have attached a representation of the character I drew:
This character is used many times over in the grammar book I'm reading, mostly in example sentences on 把 usage. The only time it occurs with any kind of context is 他有的時候把[X]當糖吃. Can anyone tell me what this character means and how it's pronounced?
