I had anough difficulty when I used to teach school (math, Comp Sci)
trying to get kids to realise that the actually had no clue what most of
the words they used everyday in speech actually meant, Given that, trying
to get them to understand a page of directions or explanstions of a topic
was a lost cause. They had no chance -- they didn't understand what three
quarters of the mono- and bi-syllabic words on the page meant.
Now you want to add simple grammar rules?

True. Its is comparitively easy to map from a graphical entry to an
unambiguous textual command. However I don't want to drop the texzt
interface, and given that, _and_ the graphical presentation, I am going to
have users trying to enter:
shoot the paper which is under the book which is on the table
in broken half-understood pidgen english.

Which is why I can't do this.

> shoot the paper under the book which is on top of the table
> shoot the paper which is under the book onto the top of the table

I would argue that there are no ambiguous statements expressable in
english which can't be re-stated in an unambiguous form in the same number
or less sentences, in english. It does of course take a certain command
and facility with the language however,
Think of it this way:
A good definition for a word is subsitutable for that word in a sample
sentence with no loss of meaning, context, or stretching of the rules of
Now pick something easy like:
The dog sat on the mat.
and define "sat". Its certainly do-able, but to watch many try; they're
