Most frequent duplicates

The following is a list of the 172 most common word duplicates (number after word is count of occurrences) extracted from a search of all English Wikipedia articles existing on 21 February 2006.

Most punctuation was automatically removed and so the count is unlikely to be 100% accurate. The count of single letter words is likely to be significantly affected by markup/punctuation removal and these have not been included on the list.

Some of these words occur in a context where duplication is intended, such as for emphasis: please please, blah blah, yadda yadda, very very; where the scientific name of an animal coincides with the common name: Gorilla gorilla, Homo sapiens sapiens; where the genus and subgenus have the same name: Octopus Octopus; or even part of the name, for example: Pago Pago, Dum Dum, Duran Duran, Wagga Wagga, Walla Walla, Chitty Chitty Bang Bang; or a town or city in a county, state or country of the same name: Oxford, Oxfordshire, Cambridge, Cambridgeshire, Luxembourg, Luxembourg.

The city of Luxembourg in orange is part of the Canton of Luxembourg, (add red) in the district of Luxembourg (add dark grey) in the country of Luxembourg (add light grey).
