Got it? Well, 'PIN' stands for 'personal identification number' so it is tautologous to say 'PIN number' - you are in effect saying 'personal identification number number'. The same is true for the other examples (swiped off Wikipedia).
In fact, Wikipedia has some good information on RAS syndrome, including why the name 'RAS syndrome' is itself an example of RAS syndrome.
Anyway, the reason I am talking about RAS syndrome today is because I came across a good example myself recently (as you can see from the image): 'Sainsbury's SO Organic' range of food – the SO itself stands for 'Sainsbury's Organic'. Is this a double RAS?
If you come across any further examples of RAS syndrome, double or not, do send them into us. Cheers.
