The liberty of deviation from the dominant word order in Esperanto and the natural languages is considered. Greenberg's classification of the languages according to four criteria, the liberty of word order in Sanskrit, and the norm of grammaticality in a constructed language are considered. Objection is made to St. Clair's argument that word order cannot be free in Esperanto, because it is not free in any natural language. It is contented that Esperanto has a far smaller liberty of word order than Sanskrit, but--except with respect to the prepositions--a far greater liberty of word order than English. The notion that Esperanto is most comparable in its degree of liberty of word order to Latin, Greek, and Sanskrit is criticized. (SW)
