Etymology: Chemists built this term from pieces with very different ancient histories. The "di-" comes from the Greek prefix "dĭ-", meaning "two," which goes back to the Proto-Indo-European root for "two." It is the same prefix that appears in words like "dioxide," and it signals that the compound contains two of the units named after it. The rest of the word runs through a salt. Greek "Ammōn" named the Egyptian god Amun, and Latin "ammoniacus" was applied to a salt associated with his worship. That ancient name gave English "ammonia," and chemists then used "amide" for a compound derived from ammonia. "Imide" follows the same pattern, adding a further step in the chemical family. The final "-ide" comes from Latin "-idus," a suffix that English adopted for chemical names. Joined to "imide" with the prefix "di-," the term denotes a compound built around that imide structure.
