Did you know?

Consequential dates from the 17th century and can be traced back to the Latin verb consequi, meaning "to follow along." Consequi, in turn, combines the prefix con-, meaning "through" or "with," and sequi, meaning "to follow." The English words sequel, second, and suitor are among the offspring of sequi. Henry Fielding's 1728 comedy Love in Several Masques introduced the meaning of "important" to consequential, which had until that point been used primarily in the context of results. Evidence for this usage declined temporarily in the 19th century, causing its acceptability to be questioned by such commentators as H. W. Fowler; it resurfaced in the 20th century, however, and is now considered standard.
