Paupers wrote, disproving elite-only literacy
Hundreds of surviving letters written by or for the labouring poor show that writing was a working tool of people at the bottom of society, not a skill held only by the educated. The spelling was phonetic and the grammar non-standard, but the letters are coherent, purposeful, and fitted to their reader. That fact overturns the assumption that the poor survive in the archive only through records other people made about them.
