AINSWORTH (Robert), born at Woodyale in Lancashire in 1660, was master of a boarding-school at Bethnal-green, from whence he removed to Hackney, and to other places in the neighbourhood of London. After acquiring a moderate fortune, he retired, and lived privately till the time of his death, which happened in 1743. We are indebted to him for the best Latin and English Dictionary extant: he published it in quarto 1736; and in 1752, the fourth edition, under the care of Doctor Ward of Gresham College, and the Rev. William Younge, was enlarged to two vols folio.
