Sin In Akkadian the moon god was called Sin (Sîn) or Suen (Su’en). The former is the standard reading of the name from the Old Babylonian period onward, while the latter was presumably the older uncontracted pronunciation. The etymology of this name remains uncertain. One of the inscriptions of Gudea from the third millennium BCE refers to Sin as a god "whose name nobody can explain", which might be an indication that his name was already unclear and a subject of scribal speculation during his reign.
