PEN'SUM. That which is weighed out as a task; more especially applied to the labour of females, because a certain quantity of wool was weighed out daily to each of the female slaves in an ancient household, which she was expected to spin into thread for her day's work. Justin. i. 3. Plaut. Virg. Ov. and LANIPENDIA.
