Full Idea
The intentional action of including the word 'big' in a sentence does not require a prior intention to say it. What is required is that you say it with the intention of saying it.
Gist of Idea
Speech needs sustained intentions, but not prior intentions

A Reaction
This seems right, but makes it a lot harder to say what an intention is, and to separate it out for inspection. You can't speak a good English sentence while withdrawing the intention involved.
