It is well known that children acquiring Germanic and Romance languages go through an early stage at which they produce declarative sentences with a Root Infinitive (cf. (1)) which would be ungrammatical in the adult language (Stern & Stern 1928, Weverink 1989, Pierce 1992, Wexler 1994). For languages outside of these language families, little work has been done on such Root Infinitives. In the present paper we investigate the status of Root Infinitives in Modern Greek, a language which lacks an infinitive form altogether.
