The IAU catalogue's account
The formation of this name begins with one of the words used by Ptolemy to describe this star in the Almagest: καμπή, "the bend [of the river]". This was misread by the Arabs, who transliterated the word as bhmn. This, in turn, was transliterated as beemun in the Medieval Latin Almagest, which was corrupted to beemin, beemim, etc. Then in Early Modern times, the derivation of the form beemim was erroneously attributed to the Hebrew word te'omim, "twins." Subsequently this erroneous word, written as Theemim, then "Theemin," was applied as a star name to any of the various dim stars running from u1 to h Eri.

Layer of tradition and ancient-layer signal are not the dictionary authors' judgement but a keyword reading of the entry's wording. “No simple cue found” means exactly that — the parser found none — not that the name is late.
