When I first came here, this was all a swamp of structural linguistics. Everyone said I was daft to build a Universal Grammar on a swamp, but I built it all the same, just to show them.
First I built a Transformational Grammar. That sank into the swamp.
Then I built a Government and Binding. That fell over and sank into the swamp.
So I built a Minimalist Program. That burned down, fell over, and sank into the swamp.
But Recursion stayed up!
Until that pesky Dan Everett came up out of the Amazonian swamp…
Apologies to Monty Python.
