Yeah, like the word “同” there which means “and” sounds the same as "童“ (child) and "銅” (copper), as well as a bunch of uncommon words such as “瞳”, which I usually see combined with "孔” (a word for hole which you may have seen in Confucius’s name as his surname) to form "瞳孔“, meaning pupil (as in the eye, not student). And now imagine every single word could have stuff like that.
