Proto-Sinaitic (also referred to as Sinaitic, Proto-Canaanite when found in Canaan, the North Semitic alphabet, or Early Alphabetic) is considered the earliest trace of alphabetic writing and the common ancestor of both the Ancient South Arabian script and the Phoenician alphabet, which led to many modern alphabets including the Greek alphabet. According to common theory, Canaanites who spoke a Semitic language (hypothetically reconstructed as Proto-Semitic) repurposed Egyptian hieroglyphs to construct a different script. The script is attested in a small corpus of inscriptions found at Serabit el-Khadim in the Sinai Peninsula, Egypt dating to the Middle Bronze Age (2100–1500 BCE).
