On other language SEs, I often have to talk about spoken language vs written language. Those phrases can be a little heavy, and I'm looking for shorter alternatives.
My typical use case is this:
[Word A] is almost never used [in writing], but is very common [at speaking]. On the other hand, [a synonym for word A] can be used both [at speaking] and [in writing].
I'm almost sure that's not the right way to say that, how you would say it?
