Can anyone suggest glyph origin of 施?
well, according to 說文解字, 施(u+65bd)﹒从㫃﹒也聲, it should be "chopped" into 㫃(u+3ac3) &amp; 也(u+4e5f).

㫃 is a main component of oracle bone script.

so, 施 is a 形聲字 (Phono-semantic compound character), to decipher the meaning, i would suggest starting from 㫃, which is 旗在竿上飄游之形 (roughly, a flag flying on a pole).



amongst usages listed, my opinions:

殺而施之, 施 is "exhibit the corpse".

施之為孫, well, this one, do you mean the verse of 禮記﹒學記 "不陵節而施之謂孫".

if yes, 施 is "carry out" teaching, or make it simpler, "teach".

have fun :)

ps: may i ask why &amp; how do you choose these usages of 施?
