As you might now, many kanji have undergone changes over history. Some of these changes happened while kanji were still restricted to ancient China. Others are thanks to relatively recent efforts to keep commonly used kanji on the simpler side of things.
Sometimes, these changes were minimal. Swapping in a similar looking shape with one or two fewer strokes, or merging shapes together a bit. Sometimes elements were just dropped and unique parts left behind.
Other times, they barely left anything standing. Or they just said âto hell with itâ and put in something that just happens to share the same onyomi, but isnât visually similar at all.
I canât guarantee that these are the most drastic simplifications out there, but theyâre pretty darn drastic.
Well, see if you can guess which kanji these old forms turned into. (good luck)
From my experience in Japan I would say é¨ for é and ă for 瞊 are extremely common. é¨ is ridiculously omnipresent. People donât write é outside of formal settings, really.
㧠you do see now and then (saw it today at a shopâs name, btw), and I have seen a couple of Japanese people using the crazy abreviation for ĺ that looks like ă, although I surely wouldnât call it âcommonâ.
The rest Iâve never encountered in the wild. Unless we are counting Showa-themed Izakayas too. But in that case a lot of weird stuff starts showing up, so I donât really recommend it.
