Early developmental stages of deontic and epistemic modality are studied in sixteen typologically different languages from IE and non-IE language families following a functional-constructivist approach. Main issues addressed are the development of requests and evidential modality. One of the main findings is that the onset of epistemic modality is influenced by the typological characteristics of the language acquired.
