Mississippi has three sets of doubled letters, two double s pairs, and one double p pair. Tennessee also has three pairs of doubled letters in its name.
Not many words begin with double letters. A few of those that do start with double letters include aardvark, eel, eerie, llama, ooh, oomph and ooze.
