You know there are too many places to begin. And even that does not approach infinity. The combinations from say two to twenty-five, given oh a five hundred thousand word vocabulary yields a limited number of first sentences. Indeed, the formula for the number of 100-word entries possible given a similar vocabulary and sentence lengths varying from one to 100 words yields a limited number of 100-word entries. One could write a computer program to generate all possible 100-word entries.  One could blat a dinner plate to foam enrich frequently used foul mops.    But then, only some would have meaning.
