Osbern Pinnock of Gloucester[1] (1123–1200) was an English Benedictine monk of St Peter's Abbey, Gloucester,[2] and a lexicographical writer.
His Panormia, or Derivationes (Liber Derivationum), was a Latin word list compiled from about 1150 to 1180.
It contained elements of both the glossary of rarer words, and derivations (based on etymology) and so was innovative; but at this stage the two aspects were kept separate.
[3] This work was printed by Angelo Mai in 1836 as Thesaurus novus latinitatis;[4] its authorship is a later attribution of Wilhelm Meyer.
It was widely circulated, and influenced later work of Huguccio.
