what is different between ”may,maybe&may be”?

maybe 只可以用於開頭
may 可以用於句中 / 句頭(問句)
其實 may be 係2個唔同ge字,
you may be a student.
你可能是學生
you is a student
你是學生

可以咁講, 你想加可能落去,
就會咁: you may is a student
不過may後面唔可以用is,am,are 呢d
只可以用be 代替,意思仍然係"是", 亦都同is一樣係verb.
變成 you may be a student

其他句子
you may go to the toilet
當中個go字同頭先個be字係一樣,都係verb.
