Meaning

noun a region marking a boundary

noun the limit beyond which something happens or changes

noun a ceremonial or emblematic staff

originBorrowed from Middle French verge (“rod or wand of office”), hence "scope, territory dominated", from Latin virga (“shoot, rod stick”), of unknown origin. Earliest attested sense in English is now-obsolete meaning "male member, penis" (c.1400). Modern sense is from the notion of 'within the verge' (1509, also as Anglo-Norman dedeinz la verge), i.e. "subject to the Lord High Steward's authority"…
