Linguistic Note on Weakly Open Set
By analogy, an open set of $X$ might be called "strongly open"
Indeed this is common if $X$ is say, a Fréchet space.
However, in general locally convex spaces, "strong topology" has a more specific meaning, so its use may cause confusion.
It is therefore preferable to call the topology on $X$ the original topology, and open sets of $X$ originally open.
