The correct spelling is gnaw.
Knaw is not a word in English. It is a misspelling, likely caused by the unusual way gnaw looks on the page — that silent g at the front throws people off.
Why Does Gnaw Start With a Silent G?
English has a cluster of words that begin with gn- where the g is completely silent. You pronounce gnaw exactly as it looks phonetically: naw (rhymes with saw and law).
This silent g pattern comes from Old English and Germanic roots. In Old English, the word was gnagan, and the g was actually pronounced back then. Over centuries of spoken English, the g dropped out of speech — but the spelling stayed. The same thing happened with words like gnome, gnat, and gnu.
So the g is not a typo or an oddity. It has always been part of the word. It just stopped being spoken.
What Does Gnaw Mean?
To gnaw means to bite or chew on something repeatedly, usually with the front teeth. The biting is persistent — not a single bite, but steady, grinding, wearing-away chewing.
It works in two main ways:
Literal use — biting on something physical:
- A dog gnaws on a bone for an hour without stopping.
- Mice had gnawed through the corner of the cardboard box.
- She gnawed the end of her pencil while thinking.
Figurative use — a feeling that wears at you slowly:
- Guilt gnawed at him for days after the argument.
- A sense of dread gnawed at the back of her mind.
- The unanswered question kept gnawing at her.
The figurative use is very common and completely natural in everyday writing.
Common Forms of Gnaw
| Form | Example |
| gnaw | I always gnaw on carrots when I’m nervous. |
| gnaws | The puppy gnaws on everything in sight. |
| gnawed | The beaver gnawed through the trunk overnight. |
| gnawing | There was a gnawing worry she couldn’t shake. |
Note that gnawing works both as a verb form and as an adjective — a gnawing pain, a gnawing doubt, a gnawing hunger. All correct.
Why Do People Write Knaw?
Two things probably drive the confusion.
First, the gn- combination looks almost wrong to modern eyes. Because the g is silent, writers sometimes feel the word should just start with n — and when hunting for a consonant to put before the n, k is an easy reach. English does have several words where k is silent before n: know, knee, knight, knock, knife. That kn- pattern is familiar, so the brain reaches for it.
Second, gnaw and the invented knaw sound identical when spoken. If you only ever heard the word and never read it, either spelling might feel plausible.
Neither knaw nor naw (as a spelling for this word) appears in standard dictionaries. The only correct form is gnaw.
A Simple Way to Remember
If you can remember gnat — that tiny biting insect — you have an easy anchor. Both gnat and gnaw start with a silent g, both relate to something small and persistent, and both are spelled the same unexpected way. A gnat bites. To gnaw is to bite. Same silent g, same logic.
