# Repetition

Two or more words/characters that are consequtive and clearly are typed by mistake. They are usually typos due to an inattention. Note that the lower/upper case is ignored.

There are three categories based on what is repeated:

* **alphabetic** - repeated character (“Hellllllllllo“)
* **nonalpha** - repeated punctuation (“Hello ??“)
* **word** - repeated full word (“Hello hello“)
