Four ordinary words that used to mean something else
Awful once meant awe-inspiring, nice could mean ignorant, silly could mean happy or innocent, and naughty described someone who had naught. Modern meanings are later chapters, not corruptions.
Words do not receive their meanings once. A community uses them, bends them, narrows them, softens them, and sometimes sends them somewhere their earliest speakers would barely recognize.
This is semantic change. It is not decay, and the earliest meaning is not the secretly correct one. A word's history explains how it arrived; a current dictionary records where it lives now. Occasionally both meanings survive at once and the word ends up facing two directions.
Awful: full of awe
In Middle English, awful could describe something worthy of awe: frightening, commanding, or deeply reverent. That older sense survives when a historical writer mentions “awful majesty.” Because awe itself mixed wonder with dread, the negative side was already present. By the late 18th century, awful was widely used for the extremely disagreeable. The path from overwhelming to terrible was shorter than it looks.
Nice: ignorant, then exacting, then pleasant
Nice entered English through French from Latin nescius, “not knowing.” Early senses included foolish and ignorant. It then accumulated meanings such as fussy, precise, delicate, and refined. A “nice distinction” still preserves the sense of careful discrimination. The broad modern meaning, pleasant or agreeable, did not become dominant until much later.
Silly: blessed, innocent, pitiable, foolish
Old English sælig meant happy or fortunate and is related to a word for happiness. Over time, the meaning moved through innocent and deserving of pity, then weak or helpless, and finally foolish. This was not one sudden reversal. Each step leaned on a possible judgment about the last: innocence could look naive; helplessness could be treated as lack of sense.
Naughty: having naught
The root of naughty is naught, or nothing. A naughty person was once needy or had nothing. The word then took on moral disapproval, describing someone wicked or badly behaved. Its severity later softened in many contexts. A naughty child has usually misbehaved; a “naughty dessert” is merely an indulgence with a wink.
Old meanings are evidence, not rules
Etymology can sharpen a word, but it cannot overrule the people speaking it. Insisting that awful must mean awe-inspiring because it once did is an etymological fallacy. By that logic, a nice person would be ignorant and a silly joke would be blessed.
The better pleasure is to notice the route. Meaning often changes by small, human judgments: reverence shades into fear, precision into refinement, innocence into foolishness. Sometimes the judgment is social rather than semantic, which is how villain, churl, and boor all began as words for rural work. A dictionary entry looks like a list. Behind it is a long argument conducted by millions of speakers.
