The name August is a girl's name of Latin origin meaning "majestic, venerable". August and is often added to lists like Boy Names for Girls and discussed in our forums with posts like "Generation CAF #51 (w/ occupations)".
From the experts:
Though associated traditionally (and fashionably) with boys, it has been used occasionally for girls as well -- by Garth Brooks, for one, along with more than 100 other parents in 2011. In fact, August is used significantly more often for girls these days than traditional feminine variations Augusta and Augustina. But there are still six boys named August for every girl, a gulf we predict will only widen.
