On the basis of Sabellic forms such as Vestinian didet, the linguist Gerhard Meiser proposed that the laryngeal reflex /a/ in the final syllable was replaced by the thematic vowel /e/ by the time of Proto-Italic, reconstructing a form *di-de-ti- from *didati. The linguist Dag Haug argues that this is unlikely as it would require present forms such as *didat to be replaced by forms such as *didet, complicating their eventual evolution into Latin present forms such as dat. Although this could be explained if Latin continued the aorist forms, Haug considers this unlikely as the reduplicated present form surfaces in Latin terms such as reddō. Instead, Haug explains the Sabellic forms as originating from a sound shift restricted to the Sabellic languages.
