I believe that the misplaced query is due to the translation of 'feathers' into the Kaqchiquel language. But this would not be the correct dictionary.
PLUMAS KAQCHIKEL kaqchiquel is a Mayan (or Mayan) language, of the quiche group, spoken in Mesoamerica, especially in Guatemala, Belize and Southern Mexico. Pen is synonymous with writer, then the expression means writers in the Kaqchiquel language.
