presider

The word "presider" is built upon the verb "preside", which entered English in the early 15th century from Latin praesidēre, meaning "to guard, direct, govern, preside over". This Latin verb is a compound of prae- ("before") and sedēre ("to sit"). The literal image is of someone "sitting before" others, implying a position of authority, leadership, or supervision. The agent suffix "-er" was later appended to form the noun "presider", designating the person who occupies that leading position. Thus, the modern abstract meaning of one who leads a meeting evolved directly from the concrete concept of the authoritative figure seated at the front.
