Pretty good with loves and writes. But now try it with acquaintance 
and meeting (I can't use 'met' as I mustn't use a verb):

Everything that acquaintance something meeting it.

Everything that meeting something is an animal.

I don't think it is possible to do this with a wide range of likely 
property names without it either being often incomprehensible, or 
else requiring NL-level complexity in the parser. People have been 
trying to do this kind of thing for many years (COBOL was an early 
example) and it has never worked satisfactorily.
