Francis Junius, Etymologicum Anglicanum, ed. Edward Lye (Oxford, 1743).
This is the first systematic etymological dictionary of the English language by Francis Junius (1591-1677), a German pioneer of Germanic philology, edited and posthumously published by Edward Lye (1694-1767), an Old English and Germanic philologist.
Junius, on his death, bequeathed his books, manuscripts, types (called Junian types), and other things to the University of Oxford, which included the manuscript of this dictionary. Lye, the last of many Anglo-Saxonists inspired by Junius, edited this dictionary based on the manuscript, adding an Old English grammar based on George Hickes's Linguarum veterum Septentrionalium Thesaurus Grammatico-criticus et Archaeologicus. Later, Lye compiled, based on Junius's Latin-Old English glossary without acknowledgement, an Anglo-Saxon dictionary, Dictionarium Saxonico- et Gothico-Latinum, posthumously published in 1772.
