Sabaean is attested in some 1040 dedicatory inscriptions, 850 building inscriptions, 200 legal texts and 1300 short graffiti (containing only personal names). No literary texts of any length have yet been brought to light. This paucity of source material, and the limited forms of the inscriptions has made it difficult to get a complete picture of Sabaean grammar. Thousands of inscriptions written in a cursive script (called "Zabur") incised into wooden sticks have been found and date to the Middle Sabaean period; these represent letters and legal documents and as such include a much wider variety of grammatical forms.
