There are a few Coptic names of the city. ''Ti•kash•roomi'' () is attested as early as 1211 and is a calque which means 'man breaker'(, 'the' + (, 'to break' + , 'man') which is akin to Arabic ''''.  () or  () is another name which is a corruption of Greek name of Heliopolis (). Some argue that  () or  () is another Coptic name for Cairo, although others think that it's rather a name of an Abbasid capital Al-Askar.  () is a popular modern rendering of an Arabic name (others being  Kairon and  Kahira) which is modern folk etymology meaning 'land of sun'. Some argue that it was a name of an Egyptian settlement upon which Cairo was built, but it's rather doubtful as this name is not attested in any Hieroglyphic or Demotic source, although some researchers, like Paul Casanova, view it as a legitimate theory. Cairo is also referred to as  or  , which means Egypt in Coptic, the same way it's referred to in Egyptian Arabic.
