Did You Know?
Both emblem and its synonym symbol trace back to the Greek verb bállein, meaning “to throw.” Emblem arose from embállein, meaning “to insert,” while symbol comes from symbállein, Greek for “to throw together.” Bállein is also an ancestor of the words parable (from parabállein, “to compare”), metabolism (from metabállein, “to change”), and problem (from probállein, “to throw forward”). Another, somewhat surprising, bállein descendant is devil, which comes from Greek diabolos, literally meaning “slanderer.” Diabolos in turn comes from diabállein, meaning “to throw across” or “to slander.”
