History
Etymology
Learned borrowing from Latin Īsis from Ancient Greek Ἶσις (Îsis), from Egyptian st-t:H8-B1 (ꜣst).
Back-formation of the Latin Tamesis (“Thames”), from the assumption that the word was derived from a compound of Thame (“A tributary of the Thames”) and Isis. The prison was named after the river.
(Salafist group): An acronym of one English translation of one of the group's Arabic-language names, الدَّوْلَة الْإِسْلَامِيَّة فِي الْعِرَاق وَٱلشَّام (ad-dawla l-ʔislāmiyya fī l-ʕirāq wa-š-šām, literally “the Islamic State in Iraq and Syria”). Compare ISIL, which translates الشَّام (aš-šām) as “the Levant” rather than “Syria”.
From the genus name.
