I actually think of her as a late 2nd generation visual myself. It depends on how you see the generational split.
In my view AOA straddled the line between generations, debuting at the end of 2nd and carrying over much of a 2nd generation sensibility (e.g. tapping the 2nd gen sexy wave.), and experiencing a bulk of their prominence prior to the entrance of the primary girl groups that are generally considered the defining top players of 3rd generation (TWICE, BLACKPINK, RED VELVET).
So in that sense, I see AOA as more 2nd Gen group. This is how I categorize them personally.
But my answer was assuming they are considered a (early) 3rd gen group or grandfathered in as a Transitional generation group. This aligns with Wikipedia view and I assume the view of the user I was responding to.
It's one of those things that depends on who's generational timeline you go with. I've seen AOA placed both in 2nd gen and 3rd (as an early player). So I was allowing for that disparity in my answer.
Ah, I see. Good point!
