Difference between "avenge" and "revenge"

[Hanifasmm]

Hi everybody,
Could anyone explain the difference between "avenge" and "revenge"
and also between "avenge on" and "revenge on".
Please give some examples of usage of both words differing in usage.
In Oxford dictionary, I find the following sentence
marked as wrong sentence.
"She vowed to revenge her brother's death."
In what way is this sentence wrong grammatically?
Thanks,
Er. S.M.M.Hanifa

"She vowed to avenge her brother's death."

Avenge is to take revenge,.

We avenge a wrong-doing by taking revenge.

Mr. Kitosdad,
Could I correct the following sentence -
"She vowed to revenge her brother's death."
as
She vowed to be revenged for her brother's death.
She vowed to take revenge for her brother's death.
Are these two corrected sentences by me correct grammatically?
Thanks,

Mr. Alan,
1. Don't revenge them. = Don't avenge them.
2. Don't revenge on them. = Don't avenge them.
3. She avenged her brother's death. = She revenged her brother's death.
If each pair is not equal in meaning, please guide me to correct.
This will help me to understand the difference in meanings
of 'revenge' and 'avenge' while coining sentences.
