The explosion of the Islamic State (Isis) into popular consciousness over the past year has also introduced a whole new lexicon.

Media coverage of the radical group often includes Arabic terms or Quranic and Middle Eastern historical references, which many English speakers may still find confusing. For those who are baffled by the myriad new terms and phrases, IBTimes UK has put together a short glossary of the essentials.

Islamic State leader Abu Bakr al-Baghdadi believes he is the eighth Caliph.

Caliphate: an Islamic State governed by a Caliph according to Sharia law. After the four Caliphs that succeeded Mohammed, three main caliphates have been established in history, although not all Sunnis recognise them as legitimate. They are the Umayyad Caliphate, the Abbasid Caliphate and the Ottoman Caliphate.
