Another interesting thing along those lines:
Even though the form of 有 is the same in simplified and traditional Chinese, our analysis is different.
有 was originally a hand (又; now ) holding a piece of meat (肉; now 月).
The ROC standard differentiates between 月 (moon) and ⺼ (meat; a component version of 肉). Those are two different components, with two different origins. That is, 月 cannot mean "meat" in the ROC standard. So in our analysis, 月 is an empty component in this character in traditional Chinese, because in order for it to be a semantic component it would have to be written ⺼.
The PRC standard writes both components as 月. It's
one component with two different origins. That is, 月 can mean either "moon" or "meat" in the PRC standard. So in our analysis, 月 is a semantic component in this character in simplified Chinese.
The Chinese writing system is complex, but that's part of what we love about it.
