Why is dative used in this case? What is the difference between this and "Ich bin sicher"?
- Loptt100September 2015
Dative case is used here because "sich ... sicher sein" (to feel certain/confident) is a reflexive verb and "sein" always wants the reflexive pronoun in dative. "Ich bin sicher." as the shorter form is also allowed and generally used in common speech but can also mean 'I am safe.' which is not a reflexive verb anymore and therefore doesn't need a reflexive pronoun in dative case. So, don't let both phrases confuse you and pay attention to the respective context.
Additonally: "Ich bin sicher" = "Im safe"
"Ich bin mir sicher" = "Im sure"
However: "Ich bin (mir) sicher, dass ... = Im sure that ...
So it depends whether or not this sentence is used alone and (sometimes) on the context of the following sentence.
All in all, you can use both sentences but the second one can cause misunderstandings.
Im not sure but "Ich bin sicher" sounds as if something is missing. Despite that, the verb you are actually using is "sich sicher sein". So, its a reflexive verb.

”Sicher sein” betrifft äußere Umstände und ”sich sicher sein” bezieht sich auf die (eigenen) Überzeugungen und Erinnerungen.
Außerdem bedeutet ”sicher” sowohl ”safe” als auch ”secure”.
