The following Proto-Sinaitic pairs of signs probably merge into (>) a single sign in Proto-Canaanite inscriptions: d and z > z ḥ and ḫ > ḥ š and t > š
The question mark (?) when found in the signs column means that the sign itself is uncertain, when found in the names column means that the name (or its meaning) is uncertain. Three dashes (---) mean that the related sign does not exist.
The list of symbols was compiled following the suggestion of Hamilton 2006 and Albright 1966
