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 his industry for a Latin and English Dictionary, which has been much used in schools: he published it in quarto 1736; and in 1752, the fourth edition, under the care of Dr Ward of Gresham College, and the Rev. William Young, was enlarged to two vols. folio.
