# example of weakly inaccessible cardinal that is not a strongly inaccessible cardinal

As I study through inaccessible cardinals, I find many examples that show some cardinal being both weakly inaccessible and strongly inaccessible.

So, can anyone show me the example of weakly inaccessible cardinal that is not strongly inaccessible?

Thanks.

Suppose that $\kappa$ is a strongly inaccessible cardinal, now force the continuum to be $\kappa^+$.
In the generic extension $\kappa$ is still a limit cardinal and still regular. However it is not a strong limit, so it is just weakly inaccessible.
