So, you can use that kind of word repetition to make any word plural in old Turkish. Which of the old European languages has such a characteristic seen? If you only think about this particular issue of diversity and frequency in this respect, you would not even want to compare with English. No way.

That is indeed the kind of systematic reduplication we are looking for. But how often does it appear in a text? Do they always say "book book" for "books", or is this use exceptional?
