## From Terror to Triumph
The word *terrific* began its life as a weapon — a descriptor for whatever had the power to make a person shake. Its root is the Proto-Indo-European stem *\*tres-*, meaning *to tremble*, which produced Latin *terrere*, to frighten, and from there the adjective *terrificus*, compounded from *terrere* + *facere* (to make): literally, *making-frightening*. When the word entered English in the 1660s, it carried that Latin payload intact.
## The Original Semantic Weight
The 17th-century English speaker who used *terrific* meant something unambiguous: this thing causes terror. A terrific storm was one that might kill you. A terrific beast was one that made you flee. The word occupied the same negative space as *dreadful*, *terrible*, and *horrible* — all of them intensity markers saturated with threat.
Of these cognates, *terrible* (from Latin *terribilis*, also from *terrere*) has held its negative ground more stubbornly. Yet even *terrible* has begun to slip: *terribly good* is now unremarkable English, and Yeats's phrase *a terrible beauty* is considered high poetry rather than contradiction. *Terrible* has not ameliorated wholesale, but it has developed what linguists call an *ironic intensifier* function, lending its force to positives when the speaker wants dramatic weight.
*Terrific* went further. By the 19th century the word had softened its semantic edges; by the 20th it had crossed into the positive register entirely. A *terrific idea* today is simply a very good one. The terror is gone.
## A Structural Account of Amelioration
From a Saussurean perspective, the sign *terrific* is constituted by its relations to other signs in the system — not by any intrinsic bond between the sound-image and the concept of terror. Once the lexical field shifted, once *frightening*, *horrifying*, and *terrifying* colonised the negative-intensity zone more exclusively, *terrific* was freed to drift. The system, not the word's etymology, determined where it could land.
The mechanism at work is *semantic bleaching through intensifier use*. When speakers reach for a word to amplify — to signal that something is extreme, that it surpasses the ordinary — they mine the existing stock of strong evaluatives. *Terrific* was available: loud, emphatic, formally impressive. Used repeatedly as an intensifier (*a terrific amount*, *terrific speed*), its original semantic feature — the feature +[TERROR
## The Awe Pair: Awesome and Awful
The clearest structural parallel is the fate of the *awe* family. *Awesome* and *awful* share an identical etymological base — Old English *ege*, awe, dread — and both began as synonyms: *full of awe*, *inspiring awe*. They diverged in opposite directions.
*Awful* took the negative path. It picked up the sense of *bad, unpleasant*, probably because awe in its older sense leaned toward dread, and retained that value as a generalised pejorative. By the 18th century *awful* was firmly negative.
*Awesome* followed the trajectory of *terrific*: first an intensifier, then an ameliorant, arriving in late 20th-century usage as enthusiastic approval. The root is identical; the fate of the sign is not.
What determined the divergence? Partly the formal sound of each word — *awesome* ends on an open syllable that feels expansive; partly the social registers in which each word was most frequently deployed; partly sheer contingency. The sign is arbitrary, Saussure reminds us, and the path of semantic change is shaped by the system of differences rather than by the inner logic of the root.
Intensity words are particularly vulnerable to this kind of bleaching because they are used so often and so broadly. A word that means *very* is pressed into service constantly, and constant use erodes specificity. *Very* itself derives from Old French *verai*, true — it once meant *in truth*, *genuinely*. Now it is almost colourless. *Terrific*, *awesome*, *dreadful* (now merely *very bad
The pattern is systematic: high-frequency evaluative intensifiers tend to bleach their original polarity, retaining only the feature [+EXTREME]. Where they land — positive or negative — depends on the surrounding system at the moment of bleaching, not on their roots.
## What Remains
The PIE root *\*tres-* still trembles faintly inside *terrific*. The word carries its archaeology with it — visible to the etymologist, invisible to the ordinary speaker saying *that was a terrific match*. This is the normal condition of language: the sign moves, the root stays. Etymology records the displacement; structural analysis
