Hi Abdullah and Momohime,

Actually 'おる' is extra modest form and if you use it to others it shows your light disdain to that person. So it's better not to use it to others, but as it happens, many Japanese natives use it with 'られる' as honorable form like 'たべておられる' by mistake.

'おる' was made from 'いる' and 'あり' and compounded together in the past but the meaning is almost same as 'いる'. It used mainly as te-form 'ておる', but it is also used for animals.

In general, aru is for inanimate objects, iru for living things. It basically means "to exist," "to be." These are the dictionary forms of arimasu and imasu.

Hi, abdulla, momohime, as i_nori says, ’おる’ is an extra modest form of saying 'いる' in this case i think it is a extra modest way saying 'ている' another thing is that 'おる' is and old way of saying 'いる' you would come across this usage a lot when you watch jidaigeki.
