Did You Know?
Ask a Frenchman named Jacques his name, and you may very well get the reply, “Je m’appelle Jacques.” The French verb appeler means “to call (by a name),” so Jacques’ answer literally translates to “I call myself Jacques.” Knowing the function of appeler makes it easy to remember that appellation refers to the name or title by which something is called or known. Appeler and appellation also share a common ancestor: Latin appellāre, meaning “to call upon, name, or designate,” formed by combining the prefix ad- (“to”) with another verb, pellere (“to beat against, push, or strike”). Appellāre is also the root of English’s appeal (by way of Anglo-French and Middle English), as well as appellate, which is used to indicate a court where appeals are heard.
