  • I am seeking a definition for this word, but agree that it may be a dord. Can't find anything at all that it could be except an abbreviation for "atomic mass unit".

  • This is in OSPD3, but I think it's an error; it's an abbreviation for atomic mass unit, often written in lower case, but pronounced as letters, not amoo. Does anyone know what dictionary OSPD picked it up from? It could be another dord.
