Accepted Answer

['ælɔɪ] 
alloya mixture containing two or more metallic elements or metallic and nonmetallic elements usually fused together or dissolving into each other when molten
You may have heard of aluminum alloy on a car. What that means is that there is another metal mixed in with the aluminum, to save money and/or to strengthen the wheels. The wheels are an alloy (a mix), rather than pure.
In addition to indicating a dilution of one metal with another, alloy can refer to the dilution of a feeling or a quality. Knowing that you look awesome in your Halloween costume would be an alloy to the embarrassment of showing up to a party where you are the only one in a costume.
