Nowadays, it is quite common to hear the words like ISIS, IS and ISIL since everyone is talking about the threats of terror attack.
As reported in Mirror, in the wake of the overwhelming terror attacks in Paris on Friday, we have seen another word being utilized with frequent recurrence.
When French president Francois Hollande addressed the nation Saturday following the Paris massacre, he said they were "waged by a terrorist army, a jihadist army, by Daesh, against France."
Hacker group Anonymous also incorporated the word 'Daesh' in a tweet published yesterday in which they pledged to 'wage war' on Islamic State.
"Make no mistake: #Anonymous is at war with #Daesh. We won't stop opposing #IslamicState. We're also better hackers. #OpISIS"
What is "Daesh"?
According to Arabic translator Alice Guthrie, "D.A.E.SH is an Arabic acronym formed of the same words that make up I.S.I.S in English: 'Islamic State in Iraq and Syria', or 'al-dowla al-islaamiyya fii-il-i'raaq wa-ash-shaam'."
In Arabic, the word can mean "to trample down and crush." But it can also mean "a bigot." ISIS has reportedly threatened to cut out the tongues of anyone it hears using the term.
Evan Kohlmann, a national security analyst, told NBC: "It's a derogatory term and not something people should use even if you dislike them."
ISIS declared that it is responsible for the series of terror attacks which left 129 people dead in Paris.
President Hollande promised to destroy the terror group in the wake of Friday's attacks, with France dropping 20 bombs on an ISIS fortress in Raqqa, Syria, last night.
Meanwhile, the manhunt continues to capture suspected terrorist Salem Abdeslam who is believed involved in the attack claiming almost 100 lives and left many injured.
There were two suicide attacks and a bombing close to the Stade de France stadium, shootings at restaurants and a massacre inside the Bataclan theatre where US rock band Eagles of Death Metal were playing on Friday.
The Foreign Office issued an emergency phone number for people with concerns about British friends or relatives in Paris - 0207 008 1500.
