Perpend isn't used often these days, but when it does show up it is frequently imperative, as in our second example. As such, its use can be compared to the phrase "mark my words." "Perpend" arrived in English in the 15th century from the Latin verb perpendere, which in turn comes from pendere, meaning "to weigh." Appropriately, our English word essentially means "to weigh carefully in the mind." "Pendere" has several descendants in English, including "append," "compendium," "expend," and "suspend." "Perpend" can also be a noun meaning "a brick or large stone reaching through a wall" or "a wall built of such stones," but that "perpend" comes from a Middle French source and is unrelated to the verb.
