Arabic name آخر النهر (āḫiru ʾn-nahr) meaning, the End of the River; originally used for θ Eri that was considered the end of the river in the ancient star catalog (Almagest). The name was transferred to α Eri in early modern times (around 1600) when the constellation was extended south to this new terminus.<ref>Kunitzsch, Paul; Smart, Tim (2006).

==Etymology and History==
In Ptolemy's Almagest (137 CE), the last star in the list of stars in the constellation The River Ποταμοῦ ἀστερισμός (modern Eridanus) is given as:
{| class="wikitable"
!id
!Greek
(Heiberg 1898)
!English
(Toomer 1984)
!ident.
|-
!
!Ποταμοῦ ἀστερισμός
!The River constellation
!
|-
|34
|ὁ ἔσχατος τοῦ Ποταμοῦ λαμπρός
|The last star of the river, the bright one
|tet Eri
|}
translated to Arabic this gives ...
{| class="wikitable"
!src:
!
!
!
|-
|34
|... آخر النهر
|...
|tet Eri
|}
This was abbreviated and misread in various ways in early modern time; e.g. Acermar, Achernar, Alcarnahar... and many more variants of the spelling.
