While I was looking up some origins regarding the character 失, I happen to come across three theories for the character.
The most common one a lot of sources say about this character is that it was composed of 手 and 乙 (which from what I've heard is also sound component) and it depicted a hand loosing an object.
However though when I looked up the ancient forms for this character, it looks nothing like a hand loosing an object and shows a person with their hair emphasized/stylized in a way as seen below: (ancient characters are from ccamc.org)
To which the other source (Dong Chinese) says that this character depicted a person falling down and apparently originally meant, "to stumble". In my opinion, I don't understand how this is supposed to look like a person that just fell over. If anything this more looks like a person with emphasized hair or something.
However in yet another source, Outlier Linguistics of Chinese Characters says this depicted a footprint with drops of blood surrounding it: Here in this theory though, I noticed that the oracle bone inscription of 市 is used here which confuses me a lot more since I couldn't find any ancient forms that looked like a bloody footprint. I'm not sure if this is an ancient form of 失 or 市 judging from looking at the form.
If anyone can, it would be much appreciated helping me out with this glyph origin since I'm kind of confused about the explanations a little. Thanks!
