from Latin quaedam (a certain woman), feminine singular of quidam (somebody)
EXAMPLE
“… So this Piece of his is very sweet in the Composure, and yet very tart against the sinfulness of vain Attire; wherein wanton Quaedams in those days came to that excess, that they delighted altogether in the Garb, and Habit, and roisterly Fashions of Men: This Sermon the King did greatly approve, as a fit Antidote against such corrupt Manners, and commanded it to be Printed. For the Doctor himself never wrote any thing, with intention to let the World see it in the Press, unless necessity constrain’d him. …”
From: Scrinia Reserata a memorial offer’d to the great deservings of John Williams, D. D., who some time held the places of Ld Keeper of the Great Seal of England, Ld Bishop of Lincoln, and Ld Archbishop of York
By John Hacket, 1693
