History of Companion

You may be a companion to someone without eating with that person, but etymologically you are sharing a meal with them. The word companion ultimately comes from the Latin com- (“with”) and panis (“bread, food”). The ingestible aspect of this word is reminiscent of symposium, which may be traced to the Greek word sympinein, meaning “to drink together.” But just as you may be a companion to someone without eating, you may also attend a symposium without drinking.
