Ancient South Arabian script

• It is usually written from right to left but can also be written from left to right. When written from left to right the characters are flipped horizontally (see the photo).
• The spacing or separation between words is done with a vertical bar mark (|).
• Letters in words are not connected together.
• It does not implement any diacritical marks (dots, etc.), differing in this respect from the modern Arabic alphabet.

Six signs are used for numbers:

The sign for 50 was evidently created by removing the lower triangle from the sign for 100.[6] The sign for 1 doubles as a word separator. The other four signs double as both letters and numbers. Each of these four signs is the first letter of the name of the corresponding numeral.[6]

An additional sign (𐩿) is used to bracket numbers, setting them apart from surrounding text.[6] For example, ‏𐩿𐩭𐩽𐩽𐩿‎

These signs are used in an additive system similar to Roman numerals to represent any number (excluding zero). Two examples:

• 17 is written as 1 + 1 + 5 + 10: ‏𐩲𐩭𐩽𐩽‎
• 99 is written as 1 + 1 + 1 + 1 + 5 + 10 + 10 + 10 + 10 + 50: 𐩾𐩲𐩲𐩲𐩲𐩭𐩽𐩽𐩽𐩽

Thousands are written two different ways:

• Smaller values are written using just the 1000 sign. For example, 8,000 is written as 1000 × 8: ‏𐩱𐩱𐩱𐩱𐩱𐩱𐩱𐩱‎
• Larger values are written by promoting the signs for 10, 50, and 100 to 10,000, 50,000, and 100,000 respectively:
  • 31,000 is written as 1000 + 10,000 × 3: ‏𐩲𐩲𐩲𐩱‎ (easily confused with 1,030)
  • 40,000 is written as 10,000 × 4: ‏𐩲𐩲𐩲𐩲‎ (easily confused with 40)
  • 253,000 is written as 2 × 100.000 + 50.000 + 3 × 1000: ‏𐩣𐩣𐩾𐩱𐩱𐩱‎ (easily confused with 3,250)

Perhaps because of ambiguity, numerals, at least in monumental inscriptions, are always clarified with the numbers written out in words.

Zabur inscription

Zabūr, also known as "South Arabian minuscules",[7] is the name of the cursive form of the South Arabian script that was used by the Sabaeans in addition to their monumental script, or Musnad.[8]

Zabur was a writing system in ancient Yemen along with Musnad. The difference between the two is that Musnad documented historical events, meanwhile Zabur writings were used for religious scripts or to record daily transactions among ancient Yemenis. Zabur writings could be found in palimpsest form written on papyri or palm-leaf stalks.[9][10]

The South Arabian alphabet was added to the Unicode Standard in October, 2009 with the release of version 5.2.

The Unicode block, called Old South Arabian, is U+10A60–U+10A7F.

Note that U+10A7D OLD SOUTH ARABIAN NUMBER ONE (𐩽) represents both the numeral one and a word divider.[6]
