Based entirely on original research, the Dictionary of Medieval Latin from British Sources is the most comprehensive dictionary of Medieval Latin to have been produced and the first ever to focus on British Medieval Latin. It is a definitive survey of the vocabulary of one of the mostimportant languages in British and European history. This new edition, bound for the first time as a convenient three-volume set, incorporates a small number of amendments and additions into the text originally published as a series of fascicules between 1975 and 2013.The DMLBS is the key lexical reference work for anyone reading Medieval Latin texts produced in Britain or by British authors. The period covered extends from the 6th to the 16th century. The Dictionary sets out clearly for each of more than 56,000 words the full range of meanings found in themedieval period and the kinds of linguistic contexts and works in which they appear, highlighting possible alternative meanings and allusions. Contemporary example quotations illustrate each usage. The full range of attested variant spellings of words is recorded and helpful cross-references areprovided, making the Dictionary a particularly valuable tool for researchers working on Medieval Latin manuscript sources of all kinds and on documentary sources in particular.
