   • 1853, Xosé Manuel Pintos, A Gaita Gallega:

     xa morder ti ben non podes
     con tal podrico nos dentes,
     inda no pan teño mentes
     seique non podes chanchar

     you can no longer aptly eat
     with such rottenness in you teeth,
     even bread, I think,
     probably you cannot gnaw
