When somebody says “that is their MO”, are they saying Method of Operation? I would think that they would need to say MOO… Or does MO go back to the Latin: Modus Operandi?
A dumb question, but it has been bugging me for some reason.
My understanding is that it is “MO”, which stands for modus operandi, which is translated as “method of operation”.
While AudreyK is correct in this particular case, the “of” is often dropped from acronyms with no significant harm done to anyone.
To take one notable example, United States of America == USA.
To be specific, it IS in general “MOO”. But a know a few tough bovines who hang in my hood who insist on saying “MO!”
Modus operandi
