Have you ever noticed how many abbreviations & acronyms there are where people have to or are inclined to say the last word of the group in order for it to be understood, such as 'PIN number' 'IBAN number' (international bank account number)? I have a feeling this is more common in English than other languages. Are we sloppy or overly cautious? Next we'll be saying, 'Would you like my international banking IBAN number'. Now I would like to know if there's a word for *that. (besides tautology)
