I preffer to say that Jinns are the "un-seen" entities , or better say the "hidden" entities . This could be either , or both , dimensionally hidden or just un-seen / hidden . For those dimesionally hidden , means they could be seen and materizlized once they are in our dimension .

In Arabic , Jinn consisted of the letter Jim (J) dan double Nun (N) . Jinnun , Jannun or Jinnatin . Some meanings of these combinations of letters could be :

* Jannaha - To equip with wings
* Jannasa - To naturalise
* Junna - To become mad
* Jinnatun - Madness
* Junnatun - Shield / shelter

Someother words , such as Paradise and Fetus (Jannatun dan Janiinun) consisted of these J and N letters , which have the same status meaning of "exist but unseen for the time being" .

Than we can say that these Jinns are : " Entities of the hidden community nature , and have the madness ability of 'moving' (changing its state) as of they are winged "
