The second post immediately below this one is a Cultural Literacy worksheet on pandemics. In that post I mention that one can discern the Greek word root dem within that noun, and that dem–or, as in the case of this Greek word root worksheet, dem/o and demi–means people. That said, I must make note of, and offer caution on account of, the fact that in Latin the root demi means half or less than. Now you know why espresso is served in a demitasse.
