Jean Berko Gleason
Gleason developed The Wug Test in 1958:
This is a WUG. Now there is another one. There are two of them. There are two _______.
This man zibs. A man who zibs is a _______.
The children made the pseudowords follow the rules that happen on the edge of knowing rule as she knew they would. Others believed that grownups merely handed down chunks of language—ice scattering down into the dark after sun hits the surface. But Gleason saw through the reflective glare of children’s speech to this:

He throwed the cup.

Wrong made the grammar flesh. Grammar as the right of the brain to wrong meaning into patterns. Grammar: The smell of a fourth dimension. The verb form of proliferation. The second tallest hill1. The fence that became incorporated into the bark. It’s resilient as I bash it against the stones. It fits us to the rules that rule what can fit as we rule them.
1The tallest hill is Mother Tongue.
