The word "电驴" is formed by combining the character "电", meaning "electric", with "驴", meaning "donkey", to create the literal compound "electric donkey". This term is a direct loan translation from the English "eDonkey", where "e" is rendered as "电" for its electronic connotation and "donkey" as "驴", resulting in a metaphorical name for the file-sharing network and related software.
