Another language we’ve borrowed from is Greek, mostly in the fields of science and academia. What is most confusing about Greek words is their plurals. For example, most people don’t realize that “data” is actually plural. The singular is “datum.” So we should say, “The data suggest …” instead of “The data suggests …”
Another example of a Greek word we might hear commonly is symposium. The plural is symposia.
Similarly, television is one medium for mass communication. Radio, newspapers, and the internet are media.
