Peruse means to read something carefully. It seems, however, that a good number of people think it means the opposite, to skim through something or glance at it for a short amount of time. I always find people saying that they quickly perused through something. No one peruses anything quickly! By definition, perusing something takes time. Except maybe Cat in the Hat. I suppose anyone over the age of seven could peruse that fairly quickly. But you know what I mean.
