An English Expositor: teaching the interpretation of the hardest words used in our language, with sundry explications, descriptions and discourses is a dictionary of hard words compiled by John Bullokar and first published in London in 1616 (London: Printed by Iohn Legatt). It was later reprinted under the title An English Expositor, or, Compleat Dictionary. At least 16 more editions appeared in the next 150 years.
It is significant as one of the first monolingual dictionaries in the English language.
Facsimile editions were issued: Menston: Scolar Press, 1967; Hildesheim; New York: Olms, 1971.
The "Expositor" treated Latin and Greek loanwords of Renaissance English, drawing from many contemporaneous sources, ranging from Robert Cawdrey's alphabetical and Thomas's Latin–English dictionaries to specialist glossaries. Many revised editions were published up to 1775, but John Bullokar lived to see only the second of these editions (1621).[1]
