Since this thread has died down a little, I'm usurping it to discuss common language misuses. Today, I'm featuring Latin abbreviations, which are flagrantly abused by many people.
i.e.
This is an abbreviation for the Latin phrase "
id est," which means, "that is." It is used to clarify a previous statement, just as the English phrase, "that is," is used.
e.g.
This is an abbreviation for the Latin phrase, "
exemplus gratus" (singular) or "
exempli grati" (plural). It means, literally, "a good example" or "good examples." It's used in place of the English phrase, "for example."
Some people cannot keep "i.e." and "e.g." straight. My advice to such people is for them to just use English, even though it takes more keystrokes.
cf.
Not many people know or use this one, but I find it handy sometimes. It's an abbreviation for the Latin word "
confer," which means, "compare." It means the writer is comparing something just written to something else, often something that may be more familiar to the reader, or to an external source that makes a statement or argument comparable to the present writer's.
Q.E.D.
Latin for "
quod erat demonstrandum," meaning "which was to be demonstrated." This is written at the end of a logical argument, to emphasize that the argument has demonstrated the point that the writer intended to get across. Basically, it's a pedantic way of saying, "the end."
