What does frightful mean?
"Frightful" is an adjective with two related strands of meaning. Its original and more literal sense describes something that causes fear or terror — a frightful storm, a frightful accident — evoking dread or horror in those who witness it. Over time, especially in British English, the word softened into a general intensifier meaning extremely bad, unpleasant, or shocking: a frightful mess, frightful weather, a frightful mistake. In this second use it often carries a slightly old-fashioned or even comic flavor, the kind of thing one might hear from a character complaining that a party was "simply frightful." Derived from the noun "fright," which traces back to Old English, the word belongs to a family that includes "frighten" and "frightfully." Though less frequent today than alternatives like "terrible" or "appalling," it remains a vivid, expressive choice for conveying both genuine horror and exasperated dismay.

""The traffic this morning was simply frightful," she sighed."
"Frightful" was once the height of British slang — in the early 20th century, calling something "perfectly frightful" was a posh way of saying it was simply too, too dreadful.

Etymology of frightful
"Frightful" derives from the noun "fright," which comes from the Old English verb "fricgan"-related root via Middle English "fright," ultimately connected to words meaning to scare or terrify. The adjective formed in Middle English with the common suffix "-ful," first attested in the late medieval period, originally meaning "causing fright" or "terrifying." Cognate forms appear throughout the Germanic branch, as the underlying root for "fright" shares ancestry with other Old English words denoting fear and alarm. By the 17th and 18th centuries the word had acquired its extended sense of merely "very bad," a path also taken by kindred terms such as "dreadful" and "awful."
