and a vertical line in Knife, something is cut by knife, which is Meat.
The big seal script of Meat is
The small seal script of the character is
similar to its big seal script.
But it is almost same as the small seal script of Moon
It is difficult to distinguish the small seal script Meat from that of Moon.
Next the clerical script for the character is
which is similar to character Inside (Post 249),
which is only one 人 inside.
Let's see the clerical script of Moon,
The Pinyin for character Meat - 肉 is Rou4.
I have to point out that the similarity of the two characters has great influence on related characters. Most radical 月s do not mean Moon, but Meat or body or organ or meat related. For example
肝 - liver; 肥 - fat; 肺 - lung; 肌 - muscle, etc.
We call the radical 月 to be Meat-Moon radical (肉月旁）, because it means Meat but it is written as Moon.
Fortunately, the confusions have not caused much problem. People have got used to. The reason may be because people just memorized the characters, don't know and care the original meaning of any character. Is it good or bad?
