Question: Is there any relationship between 田, 由, 甲, and 申?
- 田 (tián) = field; it seems rarely used
- 由 (yóu) = ???; I've only seen it as a radical for 油 (yóu) = oil
- 甲 (jiǎ) = nails, as in fingernails 手指甲 (shǒuzhǐjiǎ); it's also a radical in 鸭子 (yāzi) = duck
- 申 (shēn) = ???; I've seen it used in 申请 (shēnqǐng) = application
The characters appear similar, so I tend to get them confused often. It might be there's a reason these characters are similar which might help me remember them better (or there might be no meaningful relationship).
