I've noticed that, in terms of the Proto-Indo-European demonstratives, only the masculine and feminine nominative singular forms begin with ( and, respectively) and that all other forms begin with  (e.g. the corresponding accusatives  and ). Could these forms have possibly derived from earlier **stó and **stéh2, which came from original forms via s-mobile?
