  • Usually when a word has many meanings in English, they are the result of a centuries-long process, many of them washed up on the banks of oblivion by our time. In the case of mono, however, they're all new:

    (1) 1851: Mono, a Californian tribe
    (2) 1924: a picador's assistant, a monosabio
    (3) 1937: a boiler suit, especially those worn by Republican militia in the Spanish Civil War (literally "monkey")
    (4) 1959: monophonic recording
    (5) 1964: the disease mononucleosis
    (6) 1970: monochrome, black and white
    (7) 1977: a single-hulled boat, a monohull
    (8) 1979: a single-stranded fibre, a monofilament

    And it's perhaps a little surprising that no use of Japanese mono has come into English as a separate word. (The OED of course lists mono no aware under that phrase.)
