The word “grammar” shares a root with “glamour”—both descend from medieval associations with rare, occult knowledge. Grammar Girls brings together new paintings and studio objects by Molly Zuckerman-Hartung, Annie Bielski, and Rina Goldfield, each working with grammars we rarely recognize: marks shared between friends, everyday objects arranged like private performances, signs we read without knowing how. Together they make a case for the languages we live by without naming them.
