A heavy woolen blanket or cloth, especially one that is coarse or thick.
Possibly from Flemish or Dutch 'blanc' (white) combined with a diminutive suffix '-et,' suggesting something white and blanket-like, or from English dialectal usage in textile regions.
Medieval textile workers created hundreds of specialized cloth names that have mostly vanished—'blunket' is a survivor from an era when people could identify 40+ different fabric types at a glance. Your great-great-grandmother could have wrapped herself in something called a 'blunket' on a cold night.
