Etymology: "Countermarking" is a plain compound: "counter-" joined to "mark," with the "-ing" ending that turns the verb into a noun for the act. The "counter-" element comes from Old French "contre," meaning "against" or "opposite," so a countermark is literally a mark set against, or in opposition to, an existing one. In practice, it names the act of applying a second, official stamp on top of or beside a first one, most often to certify or verify a document, coin, or item of goods. The construction follows a familiar English pattern. "Counter-" appears in many verbs and nouns with the sense of opposing or answering something, as in "counterattack" or "counterweight," and "countermark" applies that sense to marking. Because the base word "mark" is very old and the compound is transparent, the term needs little further explanation beyond the meaning of its parts.
