I don’t know how often it is used these days, but if you have an idea that your students should know it and understand how to use it, here is a context clues worksheet on the adjective slipshod. It means, for the purposes of this document, “shabby,” “careless,” and “slovenly.”
Its primary meaning, as it sounds and dating from 1580, is “wearing loose shoes or slippers.” But it also means “down at the heel.” All of this is to say that this was almost certainly a Word of the Day at Merriam Webster at the height of the first pandemic surge in the late winter and early spring of 2020.
Wait: has this really continued for almost two years now?
