I accidentally clicked into Derivate vs. Derivative and flagged it as "off-topic". From my perspective, it does not appear to be about Mathematics Stack Exchange or the software that powers the Stack Exchange network. And soon it ended up being declined. Maybe I flagged for the wrong reason? As the main thrust of the post is the terminology difference between derivate and derivative, it might be more suitable to be asked on MSE. Any idea? Thanks in advance.
The bold parts are what make this on-topic:
I have encountered the term derivate standing in for derivative many times in posts. I usually edit the post to say derivative instead. But I am wondering, are their regions of the world where the term derivate is used instead?
Although the question could be phrased to make its on-topic-ness clearer. It's basically asking:
Should I continue to edit posts to change "derivate" to "derivative"? Or is this term correct?
