How to refer to this country?

In English you say: British , American , Saudi Arabian. But how to refer to a person from : United Arab Emirates?

[Dany]

These people are called Arabian

[mark in perth]

Well . . . no. 'Arabness' is an ethnicity. United Arab Emirate-ness is a nationality. A (well-educated) native-speaker would sort of know, and the guides are (a) existing names, and (b) euphony -- and this problem applies to names of people from towns and cities, etc. For example, we call people from Newcastle 'Novacastrians'; so try 'Emiratians' -- but it would be pronounced 'Emmerishuns.'
