gender linguistics
@heytanuki@snouts.online The singular definite one of the only one of those that's -sorta- new. The plural one obviously dates back ages (~1200) having been borrowed from Old Norse, but even the singular indef. is in fact slightly older (1300s onward) than the singular you (only fully settled in by the 15th cen, and alongside "thou" for a while after that), singular definite is about as old & has had a few peaks and lows in its acceptance since, the highest being ~2011 onward.
