Will dare to/has dared to/don't you dare

[Rachel Adams]

If I am not mistaken all the numbered sentences below are correct and the only difference between them is that without "to" the sentences are informal. Right?

But can I use "dare" in other tenses? For example, A. "He will dare (to) talk to her" and B. "He has dared (to) talk to he" with and without "to" and in C."I daren’t tell her about it" and D. "Don’t you dare talk to me like that again! E."How dare you ask me about that?" Can I use "to" in A, B, C, D, E?

1. "He dares to say what he thinks."

2."He dares say what he thinks."

3. "He didn't dare to talk to her."

4. "He didn't dare talk to her."

I changed the original thread a little.

[...]

1. "He dares to say what he thinks."

2."He dares say what he thinks."

3. "He didn't dare to talk to her."

4. "He didn't dare talk to her."

#1, #3 and #4 are ok. #2 is not very natural. forms without 'to' are neither more nre less formal.

#1, #3 and #4 are ok. #2 is not very natural. forms without 'to' are neither more nre less formal.

Why is it OK to omit "to" in 4 but sentence 2 is unnatural without it?
