Etymology: The most telling clue is the word "advance" itself, which English borrowed from Old French "avancier" and which traces back through Vulgar Latin "abanteāre" to Latin "ab ante," meaning "from before" or "from in front." To advance was originally to move something forward, the sense of putting a thing in front of others, and only later did it take on its modern sense of progress. The ending "-er" is an ordinary English agent suffix, inherited from Old English "-ere" and Middle English "-er," which marks a person who performs an action. An advancer is therefore simply one who advances, and the ending is a familiar pattern that attaches easily to many verbs.
