High Quality Content by WIKIPEDIA articles! The longest word in any given language depends on the word formation rules of each specific language, and on the types of words allowed for consideration. Agglutinative languages allow for the creation of long words via compounding. Even non-agglutinative languages may allow word formation of theoretically limitless length in certain contexts. Words consisting of hundreds, thousands, or even millions of characters have been coined with the goal of being ranked among the world`s longest words; technical scientific terms can run to hundreds of thousands of characters in length. Place names may not be accepted on lists of longest words despite their length. Longest word candidates may be judged by their acceptance in major dictionaries such as the Oxford English Dictionary or in record-keeping publications like the Guinness World Records, and by the frequency of their use in ordinary language.
