The name Gage is a boy's name of French origin meaning "oath, pledge". Gage is ranked #328 on our popularity charts and is often added to lists like Middle Names for Boys and discussed in our forums with posts like "A brother or sister for little Jack or Olivia".
From the experts:
Gage was part of the craze for one-syllable surnames, with associations to tasty green gage plums and the mathematical gauge.
Gage was first noticed as a character in Stephen King's Pet Semetary--though Gage Creed was far from an admirable role model. That book was published in 1983, and the movie came out in 1989, the very year that Gage hit the Top 1000.
Gage has spawned a couple of successful spelling variations, so don't be surprised to run into a Gaige or a Gauge.
