I sometimes encounter characters like 鑫, which is made of three 金 radicals, or 龘, which is made of three 龍 radicals. What are they called and is there a reason for their existence? Ive tried looking online but havent found a good resource yet.
maybe, called “三疊字”, have a look of this page
btw, the wiki page:
have fun :)
i checked a book in literary chinese, it was called “三字”. a famous (imo, only) story: three literati composed verses using “三字”, while drinking alcohol 🙀
