125-ignore v.s deny

[matilda]

Hello all

What is the difference between (ignore) and (deny) in usage?
I know their meaning according to what is written in dictionary. But I don't know where they are used and what changes in meaning they'll make.

Thanks

Matilda

Ignore means that you will not pay attention to something - you'll pretend that it doesn't exist.
(example) Your mother is asking you for the 100th time, when will you give her grandchildren?? You reply: "I don't hear you, I'm ignoring these questions!"

Deny means to protest or negate something.
(example) Someone accuses you of trespassing on their property. You reply, "I deny that accusation, I wasn't even in town on that day."

so what about refuse? (Although i didn't get the difference in the use of these two)
