Endubsar

Endubsar, literally "master scribe", is the identity of the scribe who writes and prepares the fourteen tablets of Enki (See Attestation).

Semantics
Endubsar is not a proper name but a compound of the Sumerian words: EN (𒂗) DUB (𒁾) SAR (𒊬), meaning: En, "master or lord"; dub "tablet"; sar "to write". In the, DUB-SAR (𒁾𒊬) means "scribe".

Adding En to dub-sar, could give the meaning "master scribe". Its choice of usage may also have been desired as a paronomasia where the Lord ENKI (EN) transmits unto tablets (DUB) by writ or scribe (SAR).

Inspiration
The use of Endubsar as a functional word in attested Sumerian history, has yet to be determined. Its use in Sitchen's novel may have been inspired by the Sumerian word Eduba, transcribed e₂-dub-ba-a. The eduba was the institution that trained and educated young scribes in ancient during the late third or early second millennium BCE. Eduba can be translated as "house of tablets" (Sumerian e₂ dub.ak) or "house in which tablets are distributed" (Sumerian e₂ dub ba.a), and Edubba ( 𒂍𒁾𒁀𒀀, transl: E2-DUB-ba-a) is Sumerian for "scribal school." Most of the information known about edubas comes from texts dating to the Old Babylonian period (ca. 2000-1600 BCE).
