From Euphrātēs (Greek Εὐφράτης (Euphrátēs)) and the Greek feminine adjective ending -ῐς, -ῐδος (-ĭs, -ĭdos). Compare Nīlōtis f, from Νειλῶτις (Neilôtis), feminine of Νειλώτης (Neilṓtēs).
Euphrātis (feminine Euphrātis); third-declension feminine-only adjective (non-i-stem)
Though it functions as an adjective, it has the form of an appositive noun. Used only with feminine nouns such as rīpa or gemma. Classical Latin used the genitive singular of Euphrātēs instead (e.g. "pro ripa Euphratis" and "apud ripam Euphratis" in Tacitus).
The earliest attested form is the ablative singular Euphratide, showing the oblique stem Euphratid- and a consonant-stem ending: based on this, the remaining forms can be assumed to be inflected like a third-declension noun in -is, -idis (such as prophētis, prophētidis). However, as the word is rarely used, most forms may in fact be unattested.
