Is there a and if yes what is the maximum number of radicals that can be there in a Chinese Character?
Characters can be made up of -or- contain lots of "radicals" but there will only be one that is the actual radical.
For instance the character 落 has both 艹 and 氵as components but it's radical is only one: 艹.
Characters can also have simplified & traditional radicals.
For example: 卡 has a simplified radical of: 丨 and a traditional radical: 卜 - where 丨 is obviously not a simplification of 卜. The aforementioned 落 on the other hand also has simplified and traditional radicals 艹 & 艸 --- where 艹 is just a straight up simplification of 艸.
