Basic English Grammar - Lady Di, are you a native English speaker? I am not, but yet I know the difference between using Qatari as a noun and as an adjective.

Example 1 (n) - Look, there goes a Qatari in a white Landcruiser :-)

Example 2 (adj) - I have some Qatari Riyals in my pocket.

Ok, English is not my strong-point, so I won't mind if someone says I'm talking rubbish provided you tell me what's right.
