This research studies a Sabaic inscription kept in Archaeology Section Museum - Sancā` University, and carries the no. A-20-1020. Unfortunately, its provenance is unknown. This inscription was published, for the first time, in Corpus of South Arabian Inscriptions (CSAI) without any analysis or detailed study. It deals with economic-agricultural activity. The inscription shows some people of “Hdtm” family owned domestic animals. It is possible also that they had corral, and they owned an irrigation canal. So, this inscription is considered one of the trade-agricultural activities. In contrast, the Corpus of South Arabian Inscriptions (CSAI) deals with it as a construction text. And the research tracks the semantics and syntax of the verbs and the personal names. It is dated to the Middle Central Sabaic period. This study clarifies that the personal names `ndb and r`bct are attested for the first time in the Sabaic Inscriptions, in addotion to the family/ clan name dm has the first attestation in Monumantal inscriptions and the second time in Sabaic Minuscul Texts. The study clears up the tense form `fcl of the personal name which has no attestation in Ancient Sabaic inscriptions, but it appears in the next stages.
