Abbreviation for Mega Octet, meaning megabyte in several European languages. A common sight on many an IRC channel and BBS that often causes some confusion.

Also for Magneto Optical as in MO Disc or MO Drive. Errr.. as seen in Resident Evil.

Also for Modus Operandi, or method of operation

Mo is also used in American politics as a synonym for "momentum." If someone starts their campaign early and gets people involved on a large scale quickly, they are said to have Mo, which is a Good Thing come Election Day.

But the mo I'd rather talk about is a postposition found in Japanese. It is roughly synonymous to the English words "also" or "too." For example:

Suzuki-san wa nihonjin da. Tanaka-san mo nihonjin da.
Suzuki is Japanese. Tanaka is also Japanese.
Mo can also be used in conjunction with other particles besides wa and ga. Some examples:

Igirisu ni mo ikanai.
I won't go to England, either.

Enka mo utaeru.
(He/she/I) can sing enka, too. (In this case, the mo replaces wo.)

In other cases, the "mo" indicates "every" or "any."

Doko de mo doa!
Anywhere door! (one of Doraemon's handy tools)

Itsu made mo ai shite iru.
I'll love you forever (lit. "to any when").

"NTT DoCoMo" = "NTT Anywhere"

Finally, for the sake of completeness, is what cows say in Japanese onamotopoeia, as opposed to mooing in English.


Mo (?), a., adv., & n. [Written also moe.] [AS. ma. See More.]

More; -- usually, more in number.


An hundred thousand mo. Chaucer.

Likely to find mo to commend than to imitate it. Fuller.
