If you're making full sentences anyway, the grammar of the sentence doesn't need to change much. The vast majority of the entropy is already in the words themselves.

Example sentence (generated by me, not a RNG): "the tiny hairy fish quickly paints a big scary monster".

EDIT: With 10 words, each from the 252 most common words... sentences of this type would have an entropy of more than 10^24 or 2^80. I guess "articles" are pretty much "The" vs "A / An" however, so there really are only 8 words of note...
