The name Arc is a boy's name . Arc and is often added to lists like Video Game Names for Boys and discussed in our forums with posts like "What would be the perfect twin?".
From the experts:
Refers, in literal terms, to a curved line -- as in Martin Luther King, Jr.'s famed "arc of justice." Could also be used as a reference to Joan of Arc -- Arc being, there, derived from her father's name, rather than a place -- or, conceivably, to Noah's Ark.
