Did you know?

"If you know aught which does behove my knowledge / Thereof to be inform'd, imprison't not / In ignorant concealment," Polixenes begs Camillo in William Shakespeare's The Winter's Tale, employing the "anything" sense of aught. Shakespeare didn't coin the pronoun aught, which has been a part of the English language since before the 12th century, but he did put it to frequent use. Writers today may be less likely to use aught than were their literary predecessors, but the pronoun does continue to turn up occasionally. Aught can also be a noun meaning "zero," and "the aughts" is heard occasionally for the decade at the beginning of a century (say, 1900-1909 or 2000-2009) in which the penultimate digit is a zero.
