إبليس

Etymology
Theorised to come from. Alternatively, it has been maintained to originate from the trilateral root with the meaning of "despairing [of God's mercy] or confounded [and unable to see the right course]" from the verb. This would, however, require the trilateral root to take the form if'īl which, excepting إحليل, is usually associated with words of non-Arabic origin (see إدريس, إكليل, إنجيل, إبريز, and إبريق).

Proper noun

 * 1)  Iblis, Satan; the Devil.
