Speakers of Bishnupriya Manipuri, a minority language of Bangladesh (and now Queens), prepare a song in the corner. A Quechua teacher from Peru (long resident in Brooklyn) gets ready for class at the same table where a Tsou speaker from Taiwan (now living in California) is correcting the proofs of her children’s book. A linguist in over-ear headphones edits recordings in the Gabonese language Ikota, made with the one known speaker in the city, who lives on Roosevelt Island.
